Amped DE Luke and Sidious were fighting faster than Leia could perceive, and yeah, I can totally see that, given that before his amp he's already implied to be more powerful than Vader in the Force, and is able to take down AT-ATs and impress Sidious - and this is six years after RotJ, during which he was already his equal as a duelist. Now extrapolate his presumably increasing saber skill over six years on top of massively increasing power in the Force, and it's not too difficult to believe that he could demolish the B-team. Sidious certainly took him more seriously than them.
In either case, amped! DE Luke's primary feat is fighting Sidious, so it's kind of circular to scale Sidious off of him. The more solid argument is that DE Sidious is explicitly more powerful than RotJ Sidious, who has studied the Force for two decades and drained the energies of Byss, alongside incredibly impressive feats, and then Wankatine gets put into his physical prime - yeah, he's probably above RotS Sidious as a duelist.
