For me it completely depends on my group.
I generally speaking have one of each role.

As tank when running with randoms I look at the first few (small-medium) pulls and see how the healer handles it. Using that as benchmark, I check if the healer is comfortable with larger pulls (if the DPS can handle it in my judgement). If yes? Huge pulls all the way. If not? Steady progress is progress, we won't have repeated wipes this way (and thus making it take longer).

As DPS? I prefer large pulls, mainly because I generally play Melee DPS and this will spare my TP

As Healer? Depends on the tank. If he/she isn't made of paper? Go for it.

Yesterday ran with my FC (Experienced DPS, Tank and Healer) in expert rou. We were doing triple-quad pulls and it was awesome fun. Would i do this in other parties? HELL NO! :P
