Great question, it really hits at the heart of my struggle. If you read between the lines of my post, it's clear that I think more highly of the Sony. So why am I waffling? Why write a wall of text?
I haven't been able to put my finger on it, but I just don't love the Sony. It's a very technically capable camera, its ecosystem is great, and it does disappear pretty effectively when you're using it. I don't hesitate to bring it with my on a family outing. In fact, I use it way more often than I used any other prior camera.
Maybe it's the ergonomics. The OM-1, and the Z6II for that matter, have a more comfortable grip and feel somewhat better in hand. They also have more accessible control surfaces that you can use without taking your eye off the EVF. An example includes the two buttons on the front of the body by the lens mount.
Maybe it's the responsiveness of the camera. The Sony is certainly a fast camera, but the OM-1 always turns on immediately. It will also blaze away at taking photos and seems to do so just a touch faster, granted I'm using third party glass on the Sony.
All that said, the Sony is just so easy to get great results with. I was messing around with the OM-1 and A9II yesterday while my kids were building legos. My youngest held their creation up after they completed every step, often in front of their face, and the OM-1 would consistently choose to focus on the lego. The A9II on the other hand stayed laser focused on his face much more consistently with its tracking AF.
Although my heart isn't really in camp Sony, at the end of the day it's probably better to have a reliable dance partner that you work well with than a drop dead gorgeous dance partner that steps on your toes.
Some of those are looking pretty ripe! I like to try to get a block of time to go after the bush in long chunks, but that's not always possible. How big is yours / how many do you have? We have two. One is tiny (about 3 feet tall), but the other is pretty big/bushy (10 feet tall or so). The big one takes an hour or two to pull all the seed pods off...
