If Roma is SS and Uta proves to be stronger, then Roma will be pushed down to S+. Uta is  as far as we know equal to Yomo and that was in their prime. Now seeing how much Touka was able to mature and grow more powerful, there's no way to even guess what he is capable off. Maybe it's leaps and bounds better then when he was equal to Yomo or maybe he didn't grow that much in the meantime, we just don' t know.

But we have one indirect measure and that's Irimi, who considered for her personally Hirako a big deal. Now ofcourse she was facing multiple opponents, but if not she'd probably more easily take care of Hirako, so i'm guessing Uta is a bit stronger then Irimi, since he was toying with Hirako.

Which concludes an SS.
