i was wondering whether someone could tell me the pros and cons of having:

1) a single octave fuzz pedal (mxr slash octave fuzz)

2) a micro pog with a separate fuzz pedal (zvex fuzz factory)

i would like to weigh up the options and opinions before buying.

the music i make is heavy with elements of grunge and blues.
it will be played on a MIM strat through a Vox AC15.
