I got obsessed with these lines of cameras and tried most of them over the last few years.
I found the Canonet 17 QL GIII one of the best compromises overall. There are a ton of them out there making them rather inexpensive. They have better finders than many of the other similar cameras. The lens doesn't have the prestige of some of the other cameras but is still very good - the difference between it and others isn't that big. The handling is solid.
The only other one I'd put at the same level personally is the Olympus 35 SP. Its a little bigger, louder and more likely to have meter issues but the lens is a bit better. Its the only one I'd buy over the GIII purely for the lens.
The RD would be up there but changing the aperture is a pain - buy it only if you use manual control as a last resort. And even after expensive repair to clean up the aperture, new lubricant leaked in and jammed it up 2 years later. Not worth the risk and maintenance cost. If you want the lens and don't need manual, buy a Olympus 35 DC. No aperture control issue, no sticky shutter problems, great lens. And cheap relative to the RD.
The 7sII is a great camera but has a mechanical issue which can cause the aperture to get 'stuck' at ~f11 even in manual. Ones that work are great and they are fun cameras but I'm always nervous using a working one that it has a higher chance of failure in the future.

In the end, find something that works and has ergonomics that work well for you. For me, the GIII and Olympus SP were the best compromises in the end.
