Bounty hunters easily. They already have 3 Force Sensitives that could beat any trio in this team, lol. Jango, Boba, and IG together with 2 addons roflstomp anybody on this team while the other 3 fight 3 Sith.
Hardly BH vs. Force Sensitives.

Bounty-Hunter Cade was explicitly no match for Nihl- as in, there was a large gap and Cade could maybe hold him off some, if he had a lightsaber- which he doesn't have one of! He doesn't get one of his own til visiting Ossus, he'll only be able to use one if someone else loses one.
Aurra Sing lost straight-up to Aayla Secura, who's weaker than any of the Sith.
Asajj is the only one I'd give good odds on one-on-one vs a sith here.
Of the three force users, threatwise they go Asajj > Aurra > Cade.
Keep in mind that Stryfe, while the weakest of the Hands, has quite strong TK and is precise enough to grasping someone's heart with TK, and his sabers are at the least fairly solid, he clashed with Cade a little (if, granted, Cade then set him up to be hit by Syn's grenades).
