My favorite form factor in a keyboard is 60%, and my favorite keyboard layout is that of the Happy Hacking Keyboard Professional 2 (HHKB Pro 2). I don't particularly care for backlighting. I had one backlit keyboard and I sold it. All my others are non-backlit, except some have LED indicators for CapsLock, etc.
The HHKB Pro 2 is a great keyboard with its 60% form factor and efficient/intuitive layout. It also has Topre 45g switches and dye-sublimated keycaps that are beautiful to look at and with a dry lightly textured touch. However, not everyone likes Topre switches or the HHKB layout, and the HHKB Pro 2 is one of the more expensive keyboards available.
I recently got two KBP V60 Matias keyboards, one with Matias Click switches and one with Matias Quiet Click switches. The tactility is great in both keyboards. The Matias Click is very loud, but I enjoy the auditory feedback. To me, the Matias switches feel better than any Cherry mx switch, and I have tried most of them, including blue, green, red, black, brown, and clear.
I had a Poker II with mx blues, but I sold it because I don't like Cherry switches that much and I also don't like Cherry stabilizers. In addition, because the Poker II has hardwired Pn and Fn keys, I was not able to remap all the keys to my liking. I remap all my keyboards to something as close as possible to a Mac/HHKB layout using Karabiner software for the Mac. BTW, I have one Cherry mx keyboard -- a WASD V2 87 "Barebones" with mx browns. The WASD has Costar-type stabilizers, which I like very much.
