Browns and clears are both quiet. You can make them even quieter by adding O-rings to the keycap stems.

Clears are probably my favorite so far. I despise browns. Every key press feels and sounds like two slightly rough pieces of plastic are grinding against each other. I miss the loud keys on the old IBM boards but my coworkers or family would kill me.

I like browns because I can feel the actuation. That bump is an assurance that I can proceed with the next key. And if you bottom out your keys you can always add o rings.

I bottom out like a barbarian. I think it’s fair to say that you type faster than I do if that actuation is a concern.
