In terms of game, Fed would be better. Sinner needed 5 sets to beat Medvedev who really did not have much variety in his game so would likely struggle against someone who had more variety and moved better too.
Sinner could outlast/outgrind Federer but considering how Federer beat Nadal in 5 after playing two 5-set matches in previous rounds, not sure if Sinner could outlast him either.
