I have been using ergodox keyboards for a long while, I did not like the kinesis advantage much (not split). The glove 80 looks interesting and I would try it were it not for the fact that switches are soldered.
I find that I like it but not as much as the advantage. It's harder to use. One of the problems is that I picked too stiff of a key type (MX clear). The other is that the keys are just a little further out of reach.
I like that I can customize it but I find that I don't use many of the features such as layers. I really don't like that I have to use layers to access the F keys. I use F2 all the time to rename things, and F5 to refresh webpages. One extra modifier key is not much but it seems to make the experience much worse for me.
I like that it's split so I can set it to my wider than normal shoulders but I don't like that it keeps moving. That seems to throw off my muscle memory of where the keys are. I'm in the process of making a fixed mount to correct for that.
I 3D printed the default case in the repo - I'm yet to start poking around with customising the parameters and OpenSCAD but eventually I'd like to be able to make the case to fit my hands perfectly (as it stands the default thumb cluster on the 5x6 keyboard is a bit large for me).
