i use a sunface with humbuckers. it is a beautiful thing. its also beautiful with singles coils. Having a bias control is cool and getting the input trimmed just right is part of it too.
However, if you are using a chain of pedals, its not as much fun as it should be - even if all the pedals are turned off, you can still notice the sound of the fuzzface getting contricted if any one of the other pedals has a buffer in the circuit. All fuzz faces are like this, but i think it is even more pronounced with germanium ones.
I think, unless you are a one pedal kind of guy then you would be better off with a pedal that works well in a team. Any of the big muff inspired pedals work fine (although they dont sound like fuzzfaces). I really like tho voodoo labs superfuzz too because it is a lot more defined than a muff and you can tailor its bass and mid response easily, although its extra predictability comes at the cost of a fuzzface's sensetivity to the volume control.
Wait till TGWHIF chimes in for encycolpedic knowledge on fuzzes, but what i have learned is that no single fuzz can do everything perfectly. In a 6 pedal setup, one that sounds good in a chain should be a priority.
