This side-by-side detailed comparison of the R7 and OM-1 prefers the ergonomics of the R7. What did you find questionable about the R7 ergonomics when you were using it?
A detailed review and comparison of the OM Systems OM-1 and Canon R7 crop sensor mirrorless cameras and their respective kit lenses.

Thanks for the link, it's interesting reading.
Ergonomics are very much a personal thing, and some may like the R7, but I didn't like the dial around the joystick, I found it too easy to nudge the dial when using the joystick. I'm left-eyed, which aggravates the situation. Also I found the * button awkwardly positioned, and the rear buttons/d-pad a bit cramped. The EVF is a bit of a let-down compared to the one on my R5, and has lower resolution and lower magnification than on the OM1. Apart from that, it's OK, although I would have greatly preferred a slightly larger, more rugged pro-grade body.
There also are things about the OM1 that I don't particularly like, e.g. I find the GUI and menu descriptions confusing. It does however fit my hands very comfortably, and is easy to operate. But the main attractions for me are the ruggedness of the body*, the wide choice of compact lenses, and the announcement of a 90mm F3.5 macro that goes down to 2x life size. That would be roughly equivalent on my R5 to the "compact 180mm F5.6 L IS macro" which I've pleaded for Canon to introduce. I also like the Pro Capture which is better implemented than on the R7, and the fact that the OM can focus-stack *and* merge in-camera. I've used an OM D E-M1 Mkii (bloody silly name), and the OM1 is even better. I think OM Systems will have a very bright future if they are able to market themselves better.
*I've recounted this several times in threads on dpreview, but it probably bears repeating. In 2017, while in Papua New Guinea with one of my butterfly photography groups, we had to wade knee-deep along a fast-flowing stream in order to reach some spectacular butterflies mineralising further along on the opposite bank. One of the group tripped on a small boulder and went crashing into the stream, and her OM D E Mkii crashed into the water and sunk to the bottom. It was down there for almost a minute, before she rescued it. After wiping the camera down and drying it in the hot sunshine for half an hour, the camera was found to be undamaged and working perfectly. She still has this camera, and it still works perfectly.
