Most effective factions/teams for heroic sith raid

Outside of nightsisters and that one team built around Pao (I think) which faction or team has been the most effective to deal with heroic sith raid? I typically run a gear 12 resistance team led by jedi Rey and deal a good 1 million damage (which is good for me at the current time) but I'd like to know what other unique teams work well outside of the more popular teams
