I prefer to use one or two powerful monsters, with unusual conditions to give them more tactical flexibility and avoid the "accidental cakewalk" factor as much as possible - randomly fluctuating portals bringing in neutral creartures, innocent bystanders, a split party, that sort of thing. I like this both because it's easier to run one monster and make the combat flavorful, and because I like players to come up with creative spell and ability uses for me to adjudicate ("You want to use the sorcerer's web spell as a trampoline to get up to the dragon? Okay...").
I've been trying to run larger groups lately, though, but it goes a bit against the grain.
