Earlier quoted context omitted.
It's a matter of taste I guess. I had a Yamaha and switched to Roland and much prefer the chunkier key action and the slightly brighter/compressed piano tone. Definitely important to try it in store. My absolute favourite is the Nord Grand, but it's a little too expensive.
I believe the Nord Grand uses Kawai’s Responsive Hammer III action, which is also on the much cheaper (and excellent!) Kawai ES920 portable digital piano.
You could go Kawai VPC-1 which is just the controller, and then connect it via MIDI to whatever you like. That way, you get a wooden action without paying for the sound engine (I've got my VCP-1 connected to a CP Reface):
