I much prefer a long spacebar on any board. I’ve got a Planck and another ortho with a full size spacebar and I much prefer the full size spacebar one. There’s lots of room to hit wherever; when I’m full on typing I use my right hand for space, but when I’m doing anything where I have one hand on the board and one on the mouse (CAD all day at work, video games etc at home) it’s essential to be able to easily hit it with my left. I only use one layer besides the one it normally sits at, no fancy features, and don’t really use win, alt, or right ctrl, so I don’t need lots of keys for toggling stuff. That’s just me though.
I’m on vacation right now or I would post a pic, I don’t have one readily available. It’s an AMJ40.
