Well, the bad and good thing about fuzz is that they are VERY responsive to the amps used; sounds like shit on one, and like heaven on another..
I'm a fuzz lover, and what I've had in my line-up in the past few years were:
Jimi Hendrix Systems Classic Fuzz (my main drive, loves to be boosted)
T-Rex Mudhoney (very versatile, sold it off cause it sounds crappy at the studio)
Proco Deucetone RAT (versatile, always delivers, not so amp reliant)
Electro-harmonix Metal Muff w/ Top Boost (technically it is a fuzz)
Lovepedal 200lbs of Tone (like an expensive JH fuzz, so I didn't need it)
I can tell you that all these react differently to different amps!
I can't recommend you what fuzz to use, you gotta try them yourself.. That's where you'd form your own opinions!
I can say that I don't like the Demeter Fuzzulator although it is versatile, and a sweet plus VERY quiet fuzz, the Deviever TBD to be truly disastrous (frankly I tried 2 pieces that sound drastically different!), or the Zvex Fuzz Factory to be too weak sounding IMO.. Some people swear by these pedals, but what's important is that you decide whether you'd want to or not..
