What will you mostly use it for?
The B3 Pro is the more travel-oriented choice because it is lighter and uses a smaller layout. The B6 Pro is more suitable when a numpad or additional layout options matter, and its north-facing RGB distinguishes it for users who want lighting. Gaming is a close match on the listed polling rate and connection modes. For modification, both share the same main limitation: switches are soldered and keycaps must be low-profile.
It's a tie
- Both list a 1000 Hz polling rate and 2.4 GHz, Bluetooth, and wired connectivity.
- Both are low-profile keyboards with ABS keycaps and no listed switch hot-swap support.
