Hard fight to call. Ulquiorra shouldn't have much of an impact unless I'm grossly underestimating his strength - if we're assuming his second resurrección enhances him as much as his first resurrección does, he'll be completely outclassed.
H2 Ichigo is another story. He's at least a level above R2 Ulquiorra, but he really might be stronger than that. Neither he nor Juha Bach were tested, so we've yet another case of two unquantifiable characters facing each other. If I'd need to take a crack, I'd tentatively side with Juha Bach because he's the final villain and his Vollständig has yet to be explored, but Ichigo could also believably pull off a victory too. Anyone acting as if it's an undeniable stomp in either side's favor is fooling themselves.
