I use Bulky Offense almost exclusively. The things I like about bulky offense is that it is the most versatile kind of team, with multiple different options for star Pokemon and attacking/defending combinations. Pokemon associated with bulky offense usually have many resistances as well, making team-building easier.
Stall teams have too many threats to deal with in six slots, and people often use gimmicky sweepers or wallbreakers that you won't have prepared for. Back before Platinum, stall was my favorite playstyle because it was much easier to wall the relatively limited number of threats in the metagame than to sweep with them.
Heavy offense teams are the kind I have the least experience with. I don't like to use Heavy Offense teams mainly because if they lose the momentum of the match, they will quickly be swept by one of their many team weaknesses. Heavy offense teams are also very vulnerable to losing a turn from a miss or overprediction.
