I think the terms you’re looking for are “choc spacing” and “MX spacing”. Choc spacing is what the Piantor uses where the space for each key is 18 x 17 millimeters. MX spacing is 19 x 19 millimeters.
If you want to keep using low-profile switches, there are a handful of boards that either choc or MX switches, and any of those will always use MX spacing. That said, I don’t think there are a lot of pre-built options in this space.
Maybe check out Klor. I think that one is offered as a pre-built by beekeeb and it uses MX switches. It’s got the more aggressive pinky stagger, but it also has some splay which may or may not be your thing. I just finished building one using tecsee “medium” switches and MTNU keycaps, do it’s lower profile, but still not as low as choc.
I’ve been using my bad wings (v1) for over a year, and I didn’t think I’d ever give it up. It’s a 36-key mono-body split with a cirque track pad in the middle, and I use it with a miryoku layout. I used it as my only board for several months after I first built it, but I was constantly using it for travel and project computers (it’s perfect for tinkering with raspberry pis), so I put another board at my desktop computer and now my bad wings goes wherever I go for my laptop, or hot-desking, or projects, or anything else. I’ve even used the track pad on it as my only mouse for days at a time.
I recently bought a bad wings 2 as a back up and so that I could convert my first one to wireless with ZMK. All in all, it’s been a fantastic board for me, and I’ll definitely be using it for the foreseeable future.
