Bobagums are very quiet, and they accomplish this with soft silencing pads - so they do sacrifice the crispness of a standard switch.
Box Silents make a bit more noise, but enjoy a more crisp bottom-out in comparison to many other silents because of the large, flat pads. As a bonus, they don’t interfere with any keycaps (like GMK) if the LED slot is facing the top of the board.
Silent Inks are in-between; more smooth and quiet than a Box Silent and more crisp than a Bobagum, but they aren’t immune to occasional ticking sounds.
