Cherry MX Brown and Kailh Box Brown V2 are very similar, medium-weight, tactile switches. They have a fairly small but satisfying bump to overcome before actuation. The Cherry bump is in the middle of the keystroke, while the Box Brown switch bump comes earlier and feels a bit heavier. The Kail switches also have a box design, which means they're typically more stable and durable in the long run. However, there's also a bit of inconsistency in switch-to-switch performance as they're more mechanically complex.
