According to the designer of both Filco and Leopold, Leopold should actually be better than Filco. The Duckies seem to have a great reputation, too.
As for what's crispy or crispier, that's harder to tell. IMHO the browns are also crispy, except in a different way. I'd imagine them as allowing for faster typing overall, well, certainly faster per se, not sure about speed to accuracy ratios, as I broke my only browns keyboard and haven't been able to use it since; currently typing on a blue tenkeyless Filco. I like the keyboard a lot but I'm beginning to have thoughts about browns because of the strain on my fingers. It's more difficult to avoid bottoming out than it was on IBM Model M, I think, and keyboard resistance does seem to be slowing me down compared to what if it were less, such as e.g. on browns. The browns are believed to be ergonomic because they're still tactile while providing less resistance than the blues (which doesn't necessarily translate directly into less typing effort since adjustment to insufficient resistance could perhaps also be burdensome). I suppose with both keyboards it helps to be an accurate typist since with the blues it saves you going back (which is a bit of a strain) and with the browns it allows you to keep up with the possible speed.
As far as gaming companies go, Razer has made a blues keyboard (Blackwidow, ordinary or Ultimate with lights), Steelseries the 7G and 6Gv2 keyboards with black switches (7G has a hand rest and perhaps some more stuff, 6Gv2 is minimalistic), Thermaltake a Meka keyboard with blues (basic Meka, which is compact but has all keys, Meka G1 that looks like a Steelseries 7G and is full-sized with all keys, standard layout and edges just after the last keys, Meka G-Unit that has a double column of additional keys on the left and is more sculpted than G1).

I'm also not sure which of the claims to some specific gaming-related advantages are actually unique to a particular keyboard as opposed to any mech keyboard in general.
Edit: it seems Razer has recently also released a different, Stealth edition of both Blackwidow keyboards, which seems to have 45 g force and 2 mm distance, suggesting browns. Not sure about the 2 mm distance, may be reduced compared to the normal keyboard but I don't know. Looks quite attractive to me but I'm not buying anything from Razer since they behave like a sect and I don't like that.
