I personally use an ergodox I built, and I will never type fast like I can on a staggered layout. I also had to fix a typing mistake (I typed c with my index on staggered, and it became 'b')
In the end it's the split that saved my wrists. I believe everyone should type on one, whatever the model.
ortholinear is the Planck EZ (https://blog.zsa.io/2307-goodbye-planck-ez/) for example.
this Glove80 is vertically staggered (or as they said in the review article: it has column stagger), NOT ortholinear.
My only gripes are the tenting legs sometimes close when I shift the keyb around on my desk. And it's not wireless (I don't have time to mod).
I've been using a Moonlander for about a year. I feel like it took at most a week for me to adjust and to attain my current typing speed. I probably type a little slower on it (maybe less accurately too), but my rate is passable (80-100 WPM). I've recently tried a Kinesis Advantage 2 for a few weeks and did not find that adjusting to it was very difficult.
Maybe I'm the odd one out here. Edit: having seen other comments here, I suspect I might be. Apologies for making switching seem trivial.
However over the years I’ve purchased many ergo kbs: ergo dox, kinesis and variants, and I just could not get into any of those.
Until I got the UHK (Ultimate Hacking Keyboard) , and I absolutely love it. It retains the QWERTY + regular (staggered?) layout, has split/angled halves, and thumb clusters, all of which can be programmed with an excellent software.
