I mean it could depend on one's comfort level, and what kind of maps you play.
for example, universally the most recommended choice is what NightNarumi said, since mech's keyboard tend to react way better with mania patterns (most of the time at least)
but sometimes, a good choice could be ranging for a special controller (like the pop'n mania for 9k), or using another type of keyboard like membrane, etc
for example i just use this laptop keyboard, and other than the fact that i end up jumping everywhere with the keys, its pretty good or me
IDK but yeah, whatever that suits you should be the best
