I think almost every mechanical keyboard feels the same. What makes the difference is the switches under the key cap.

Black: linear, hard, no sound. Brown: tactile, no sound. Blue: tactile, clicky sound

I use KBC Poker with red Cherry. Light, linear and no sound.

I have a keyboard with brown switches and while they are quieter than blue ones, saying they produce "no sound" is quite an exaggeration. They still have a nice clicky sound and are much louder than normal keys. I actually like this, but it is something to keep in mind.
