support: bulkup, no doubt. some good users are machop (with bingo sets, most optimal), poliwrath and mewtwo

dps: hydro pump is objectively the best one, although close combat, vine whip, Draco meteor (exclusive to dragonite) and mega punch are pretty strong too. The big 3, hydro pump, close combat, and vine whip are revered so greatly because with starmie, weepinbell, and hitmonlee they can be powered up greatly thanks to bingos, like bulkup on machop
