What is the general consensus about the EF 11-24's image quality?
I used it since its introduction until I got the R5 in 2020. My catalog of "keepers" has about 700 photos taken with it, indicating that I really liked it but I was always more of an UWA guy. On the 5DsR it was showing quite strong limitations in the corners, which is to be expected. If you mix my OCD with these visible defects and the lens size / weight I divested while I still could get good money, fully anticipating an RF replacement. I didn't know it would take four more years...
Looking forward to the 10-20 that I ordered 21:01 PDT, before the announcement email from B&H

I expect Canon have achieved record-breaking levels of vignetting with this design. Canon managed to fit a full 4 stops of vignette into the RF 50mm f/1.2; my money's on at least 5 here.

For ultra wide like this I doubt anyone could ever tell the difference between USM and STM.
My guess is that they used STM because it is smaller.
I expect that there is no technical disadvantage to using STM in this lens.
Clearly the nano USM is not that expensive if EF-s 18-135mm and RF 100-400mm can have it. Those are pretty cheap consumer zooms.
Gordon Laing says the 10-20 focuses faster and smoother than the old EF 11-24.

alot of professional photographers when they have a shoot rent everything . Especially in comercial advertising work. Dont go by what you see on youtube or social media they exist to sell crap.

From the Canon Japan media release (Google translated):
A design that takes advantage of the RF mount's large aperture and short back focus, as well as distortion correction on the camera side, has resulted in a significant reduction in size and weight.
The Canon Europe page link above has a couple 'split-view' comparisons including video that shows the stabilization difference between this lens and the 14-35. You definitely see way more IS video wobble from the 14-35.
The drone clip of the cliff shows very slight wobble noticeable at the end of the clip.

For myself it is/was part of my hiking trip kit. EF 11-24, RF 28-70, EF 100-400 MKII and I like the quality it gives.
After a longtime I finally gave in thanks to Stan's comments and got the RF 14-35. Now I interchange it with the 11-24 as part of my hiking kit.
I am mixed on the 10-20 and as I ponder how would it fit in my kit the ultawide <14 works but I also tend to shoot a lot at 24mm and thus my mixed feelings as the 10-20 by itself would mean carrying a 2nd lens for 24mm.
The 28-70 goes with me often and paring it with a 10-20 leaves a big gap.
On the other hand I like doing walks downtown amoungst the skyscrapers and a 10-20 would be useful in terms of lightweightedness. Remain mixed on this lens.

The 14-35mm is a very good lens for the price, including the size and convenience, and I liked it quite a bit, but you definitely do see that degradation at the edges of the frame, and compared to a lens like the Sigma 14-24mm f/2.8 on Sony or the Nikon 14-24mm f/2.8 (best UWA zoom I've ever used) that I shoot with now, it's just night and day better at the edges on the latter two lenses.

Just as a follow up - I went and looked at my review of the 14-35, and I said the following:
"The 14-35mm f/4L IS USM is a lens that is predominantly sharp throughout the focal range. Beginning at the wide end, the lens displays outstanding sharpness over the central 75-80% of the frame right from wide open, with softer edges and corners. Stopping down to around f/8 to f/11 raises border sharpness to good levels, with the corners still retaining a bit of softness, mostly due to astigmatism. Compared to the very best 14mm zoom lenses, such as both the DSLR and mirrorless versions of the Sigma 14-24mm f/2.8, the RF 14-35mm compares very favorably in the central 3/4 of the image frame, but lags a bit at the edges."

Do you use filters much on the 14-35? For me that could potentially be a deciding factor. Polarizer use with such an UWA could create odd effects with a lot of blue sky in the image, but ND use for longer exposures, for example. Are there decent optical quality gelatin ND filters available? Looks like you can still buy some Kodak Wratten gels at B&H. Could this also be a video use concern where variable NDs are very popular?
Back in the B&W film days I used gelatin filters with a bunch of my UWA EF zooms (such as 17-35/2.8, IIRC), but back then it was also easy to buy the Kodak Wratten gel filters, and not that costly. Just wonder what, if any impact the gel filters have on image quality now with high MP digital sensors (compared to the old film days)?

You have to wait for people to get their hands on actual rental- or retail-supplied units, so you can be sure that A) the reviewer actually has had the opportunity to spend significant time with the product, and B) they're not someone who has to worry about keeping manufacturers happy.

The RF 10-20 f/4L has a leadscrew type STM motor. This is a form of linear motor. It is near silent and can be extremely fast depending on the design. It is capable of focusing faster than the ring type USM of the older EF lenses and will be similarly accurate as Nano USM.
Nikon employs leadscrew type focusing motors in most of their Z mount lenses. Notably,leadscrew type their stepping motors in their 50/1.2 and 85/1.2 are DRAMATICALLY quieter and are just as fast if not faster than Canons RF equivalents.
These are not the same type of STM motor as is in the RF 1.8 macros, those are all gear type STM which are more compact, slower, and louder.

Have not used a filter on the 14-35. Come to think of it I haven't used a polarizer for over a year on any lens. As to wrattans I have Wrattens galore which I use in the old Canon Gelatin holders 3 and 4 inch size) when doing Full Spectrum photography with my Full Spectrum Modified R5. Heck I even got a bunch of Rosco's and cut them to size. Though all my wratten use is on the front of the lens. Thankfully a lot of my Wratten's I got off of eBay when nobody wanted them. Got some rare ones before demand set in and prices skyrocketed. One of the reasons I still like the 11-24 is I can use the drop in EF-RF adapter but the polarizer drop in did show some interesting skies with the polarizer as some images should a pattern of changing blues due to the UWA.

Keep in mind we are in an era where there are no really 'bad' lenses. Gear head reviewers are going to find only little things to criticize, mostly boiling down to preference and comments on price. The result is most reviews are either favorable and get panned for being 'bought', or come across as nitpicky and panned as such. Gordon is generally very fair and has pointed out notable missing features on other Canon preview products he has done. Add in that every single poster on the internet thinks they know what the better thing to do would have been, and such is the soup we taste on video sites, comment sections and chat forums across the world.

This 10-20 is not for me, but WOW is it so much smaller than the EF predecessor. Amazing advancement. Truly.
I don't see STM motor as a downside either. Generally the focus range of these superwide lenses is very narrow anyway, so the speed issue is probably not an issue at all. And and the couple of STMs I have on the RF mount show no difference in in-focus keepers during action shooting. Time will tell, but probably a smart move by Canon to keep the size and cost down (high cost could always be higher!).
I could see this in a lot of photographers' bags for shooting houses and other aritechture. For MLS postings for sure, this lens would do the vast majority of places.

If the focusing group is internal, rather than front barrel, STM will be plenty fast. The EF 24-105 IS STM has internal AF and was in the same ball park as the ring USM AF of the EF 24-105 4L IS USM. If AF is via front barrel extension—like the RF 85 2.0 IS STM—focusing will be dog slow.
