For Corruptors, having Kinetics as a secondary is nice. The End Drain on Transference seems to come in quite handy most of the time, making it a lot easier for people with Debuffs (Such as Rads) to lose all their End which, obviously will detoggle their debuffs. The only thing i don't like about Kinetics is that the Heal has a chance to miss. Often causing any duels or battles to end quite horribly for the Kinetic. Although some people can recover from a missed heal, its not easy. Especially with the Heal suppression. Power Boost will always come in handy with that though. :P
And for Masterminds, there's a real popular build out there atm, Thugs/Pain Domination. It seems to do pretty well. Not many things out there that can kill one.
