Well I'll give my top five fuzzes at least:
Ruiner, BB, VT, TFR and Brown Dog. I guess VT isn't technically a "fuzz" but I run gain 3/4 or so up and it's pretty fuzzed out.
If I'm being serious, no particular order:
Dunwich Cthulhu Fuzz, Dunwich Wizard Fuzz, Wren & Cuff Pickle Pie B, Magic Pedals Magick/Shrine Fuzz, smallsound/bigsound TAFM
