Thank you so much for the detailed reply.
After using the Om-1 with the 150-400mm setup for 2 months, I do miss the Sony's customisation abilities. But the 150-400mm lens is really quite unbelievable for a zoom lens. It's sharp enough wide open, and the f4.5 (or f5.6 with TC on), is really an advantage. For the Sony 200-600mm, to get great results, usually I have to stop it down slightly to f7.1or f8.
Now I wish I have 2 OM-1, one with the 12-100mm f4 or the 40-150mm f2.8, and the other with the 150-400mm. My other Olympus body is a very old EM10ii (I use it mainly for star trails for lightning, using the live composite function).

I don't have an A-1 or a 200-600 but I find the OM-1's bird subject ID acquisition to be virtually flawless.
I do have an A1 and 200-600 zoom, and I'm starting to agree with you. I think the OM-1's quad-pixel AF helps, plus in my recent low-light shooting, I think I might have been bumping up (or down?) against the A1's -4 EV AF limit - while the OM-1's AF works down to -6 EV.
I listened to an OM-1 engineer. He said that the quad pixel was used for AF and really helps. He also said that the OM-1's low light performance was dramatically improved. He compared the OM-1 to the R5 and indicated that the dynamic range was about a step worse.

And the R5 relies on backed-in noise reduction in their RAW files to achieve that better dynamic range...
I also read about how these quad pixel arrangements lessened the noise but I had my doubts after reading the explanation. The Quad pixel (quad bater in cell phone nomenclature) is apparently a big step at least for cell phones.
You are not the only photographer who compares the OM-1 to the A-1 which is simply amazing to me. A couple have even sold their A1.
I spend time on a Backcountry Gallery which was a Nikon centric forum but now includes Sony. I read about the contortions some go through to get a proper focus with the Z-9. My experience with the OM-1 is NO Problem. Usually, I shoot in ALL AF zone but go to SMALL when too many birds are in the frame. If I can see the bird the camera sees the bird. If I can see the bird's eye the camera does.

I'm starting to doubt my decision to go back to the Sony A1... because according to one expert on the Sony forum, a photo like the one below is impossible to shoot with a Sony because the shutter speed is below 1/320 of a second!
These never cease to amaze me at these shutter speeds. Well done. Are these taken single shot it or are they pro capture and choose one? Maybe that’s my problem with perched birds. I use single shot and cannot get this kind sharpness. There was an always slight blur. Great work!

Thanks!
This was shot hand-held, as are practically all of my bird photos. I usually shoot in C-AF with the mechanical shutter, and drive speed set to Sequential - Low (10 fps). Lately I have been shooting more in single-shot mode because bird detection also works well in that mode, and it doesn't leave me with hundreds of nearly identical images to cull...

That so called "expert" is more of an FM troll than a contributing community member.
Available 150-400. Just got an email from Olympus Canada saying my reserved in January. 150-400 its finally my turn to be payed for / and shipped. In May i purchased Molson's Lens and it has been excellent so as much as I would like two of them that is a bit much I dont know if anyone in Canada would be interested but PM if you might be. Just seeing if anything could be worked out for someone to get the lens instead of waiting the 11 months like I would have had to.

OK Mitesh, are you a snack, a meal or a buffet (the way the cat is looking at you I cannot tell, )?
Really great images, btw. Inspiring!!

Thanks, Bill, and fortunately for me, this family of pumas had been feasting on a large guanaco carcass (image below) for a couple days so were well fed and probably had little interest in me

I have been following the 150-400 image threads, and I find that the lens truly excells with images at close to medium distances. For larger distances, I would still prefer a 600 or 800mm lens (not using a TC). I have used the Sony 200-600mm on the A1 for about a year now, but honestly, I wish Sony made a 150-400 level zoom lens, the images have so much more finesse and optical charm. The Sony 200-600 is mainly a tool for me, but not a lens to be thrilled about. The Olympus does have that extra something.

Which lens will you be using on the A1?
I replaced the OM lens with the Sony 200-600mm G and 100-400mm GM. I need both of these lenses to cover what the OM 150-400 did, since it focused much closer than the Sony 200-600. I think to get the most out of my A1, I need to invest in the 600mm f4 GM, but the accompanying price tag is tough to swallow, and transporting it in the field is more challenging.
Using longer lenses for distant subjects gets trickier to evaluate, since the effects os atmospheric distortion can be unpredictable, and hand-holding becomes less practical... but an OM-sized 600mm f4 with built-in TC would be pretty sweet.
