You should really make your decisions on what part will function and/or perform best given your circumstances (current and future mods) and not just because you don't want to be like others. The fact that a lot of people run an item usually means that there is something to be said for the quality/performance/fit etc. of that item.
What tranny to go with really depends on what the person does (1/4 mile, track, highway) and how their car is set up (stock motor, built motor, race motor - in addition to rear gearing and budget).
