gmmk fullsize isn't terrible, since having all those keys removes it's biggest problem, which is you can't reprogram the layers at all
The main advantage of getting a nice YMD96 kit is you'd be able to use pcb mount stabs, you won't have to deal with north facing switches, and you'll be able to use QMK.
At this point, I'm pretty much uninterested in any board without QMK given how powerful and useful it is
