My all time favorite is buckling spring, they just type incredibly well. Unfortunately it's not good for gaming due to noise and hysteresis, and even just using one while watching a movie is distracting. You also have very limited options for manufacturer and shapes and styles. Alps also has some that work quite well.
For gaming, I love Jailhouse Blues, it was part of what they were created for, they have very fast reaction, low noise, and no hysteresis, pretty much everything a buckling spring isn't yet still work well for typing.
Honestly, I never really felt the hysteresis on Model M buckling springs (never had the chance to try a Model F), and would greatly prefer gaming on one to any linear switch because of the tactility. It just kinda snaps back right up once you've gone past the release point.
Cherry MX Blues, on the other hand? I can really feel the release point shifting up on those, but it's still not quite a deal-breaker for gaming. (It is, however, enough to make me prefer MX Clears overall.)
I've also never heard of a "Jailhouse Blue" until now, such that it has me tempted to test it out on my DSI Modular Mac at some point (and, in the future, the Kinesis Freestyle Edge). It'd save me the hassle of having to buy MX Clears or Zealios and transplant them all in manually.
