People are going to say its a matter of taste about switch choice for gaming.
But for competitive games and whether you throw yourself into gaming competition, i would call linear switch as most proper switch for gaming, especially on fps
Actually, it wont make you better or raise your skill, its a matter of comfort
any cheap ruber dome keyboard would be effective enough for fps.
tactile switches such as blue or brown are too unpredictable, meaning you must know when key is activated
i came from ut/quake and played it for long time, each move is important, straffing, moving is the key to surprise others good players
with brown keys, i accidentally pressed twice keys and failed my movement: i was an easy target for anyone who has good aim
if you play modern fps, then red/black would be the best choice (if you bottom out alot then linear switch does help you)
if you play all games including mmo, moba, rts, fps, any type of switch
about the choice of keyboard, its a matter of taste as well, i d rather pick Ninja imo, anyway both are great keyboard.
