The 3 is basically the same except you have real F keys and can upload settings to it via USB. Both are great keyboards. I’ve used them for well over a decade.

I went from 1's and 2's w/ custom controllers to a 360pro. It's largely the same board in terms of geometry. There are a few more keys, which are welcome, it's ZMK programmable (pro only). The writ wrests, extra, are better and don't seem to deform/wear out like the old ones. It's much less 'hollow', feels much more solid. The tenting is pretty awesome, the split is welcome. I would buy the pbt keys for extra $, the keys they ship are shit. I also pulled the DSA homerow from one of my advantages and used it here, they moved away from those special home row caps for cost reasons.
