Personally I prefer a 60% keyboard and work on a HHKB Professional 2.

Different strokes for different folks - try out different form factors and different switch types, there's a lot to see and try.

Das Keyboard is the way to go my friend. They're absolutely lovely to type on. Although any other mechanical keyboard is probably acceptable...

Yeah I love the latest Das Model S Ultimate. The aluminum plate and the keycaps feel very premium. The newer one's at work and I have an older gen at home and I much prefer the newer.

I really like my topre realforce rgb. Most solid keyboard I've ever owned. I added the optional cushions at the bottom of the stroke.

I use a Topre R2 that I imported from Japan, and I love it. The feel of typing on it is quite unique, and has replaced all my other boards.

i think filco is the gold standard in mechanical keyboards: https://www.diatec.co.jp/en/

they're built like a tank.

I own two Filco boards and they are extremely solid. Also easy to get an aftermarket controller board (and easy to fit) if you want to make it programmable.
