So I will start by saying I have not gone thru any testing as I just read a bunch of stuff online today. Generally speaking mechanical shutter is "better" than electronic for various reasons. But in a Studio setting what might be apparent with strobes. I'm asking for a couple reasons but the 1st one is I am trying to adjust the FPS for low, high, & high plus but it only makes a difference in electronic shutter mode. Canon is super vague on any real information because there are so many factors in the actual fps. Basically it seems that in mechanical low is 3, high is 6, & high plus is 12 maximum if the planets align. All the setting you think you can change are only valid in full electronic shutter mode (not even E 1st curtain). I guess I'm asking if anyone has seen any issues with shooting electronic shutter in a studio setup. I am going to guess that's the quality is still good because if you use focus stacking the camera only shoots in electronic shutter mode by default and you cannot change it.
If you want to know why I want to rapid fire in studio is for GIFs. If I can tweak the fps to just be under the recycle time of the strobes I can maximize the frames...

The FPS are listed in the manual and pretty close to accurate. MS is 1/200, ECFS (still a type of MS) is 1/250, and ES is 1/160. I tend to go 1/3 stop slower for external wired strobes. EL-1 or EL-5 flashes should work at all allowed speeds, but you cannot do 12FPS very long other than low power.
I would consider pulling frames from a video to make the GIFs, but I assume you already tried that.

I have not noticed any image quality tradeoff when using flash in e-shutter. Sometimes the 1/160 sync can be a bit of a limitation but you can use HSS to go higher, if your flash/strobes support it. But during testing of HSS at very high shutter speeds - like 1/4000 and higher - it resulted in some very slight banding with my Elinchrom ELB 500, likely due to how HSS works, combined with how the image is 'scanned' off the sensor. This slight banding was also present in EFCS and was cleared/resolved in fully mechanical shutter mode. I didn't try my Canon EL-5 so am not sure if the slight banding was a general phenomenon, or specific to the Elinchrom.

I am using Broncolor packs with Pocket Wizards. I always need to set my shutter speed 1/3 lower so I don't get banding or the black bar at the top when using ES in stacking. So I need to be at 1/100 when using ES for anything. We don't do GIFs in video because we're shooting & lighting for photos as the main job.Truthfully I think the 6 FPS is about the max we'd want, 5 is probably ideal, 3 is too slow. I will likely just have to boost the ISO and reduce pack power to get there.
