In his prime at full power, Yusuke would just be way too much. Not even Susanoo would be able to block a full-power spirit gun from an S+ class demon. Itachi's only chance is to speed blitz, but if I'm not mistaken I think Yusuke is faster (not positive, @cadencev2 would know...)
Sinestro is no more weak of a link than Apoc...in fact, I'd say Sinestro could probably crush Apoc 1v1. However, this is truly Brainiac v Ultron, and Brainiac would utterly stomp any version of Ultron. Team 1 wins.
Cap definitely solos if it's movie versions...he stood toe-to-toe with Loki for a while too, on top of the other feats mentioned here (glad I'm not the only one who realizes the insanity of being able to break submarine glass underwater...)
