I just got a Keychron K2 Pro and I'm very much enjoying it. The OSA profile keys with the brown switches are a massive improvement over the cheapo 2nd-hand membrane keyboard with the flat keys I was using before.
Even though I absolutely love the brown switches it came with, I'm excited to hot swap them out to try different switches, and see what they're like.
The Gazzew U4T have been recommended quite some. I like using it. It's a quite remarked bump over e.g. Cherry browns.
I got a single Akko Lavender Purple which I also like the feel of. Also quite crisp bump. But I only have the one, so I don't know how they are to type in.
Cheap huge bump tactile represent here: Jwick or JWK T1s. Might have to spend more to get the smoke grey version which has a transparent housing if you want the backlight to shine through.
