@shapr I'm currently prefer a Kinesis 2, tried (but wasn't overly fond of) the Moonlander, and plan on migrating to the Kinesis 360
The Kinesis is overall the most comfortable by a considerable margin. The Advantage2 doesn't support layers, which I don't like, but the 360 does.
I got the "pro" version with the open-source firmware, so I've not actually given my new 360 a serious go yet, as it's a bit more complicated to set up.
But now I can start using layers with my preferred ergonomic solution... so I may have to mod my Kinesis 2 with a new 2040-based microcontroller just to get a consistent experience between my Kine 2 and my Kine 360.
I'm pretty sure I'm not going to ever get exactly what I want without eventually going all the way and designing and building my own keyboard. The Kine360 comes close-ish, at least for the keyboards that I wish were mounted to my desk and to one of my chairs. The Kine2 is a reasonable start for a portable keyboard for sitting wherever, but does need much more serious modding in the long run.
