Let's run down the list (keep in mind I'm just basing this on the movies, haven't read any extraneous sequel trilogy content) Q99 it's less that Kylo never shows any finesse and more his actual combat feats range anywhere from nonsensical to not very good. I can see the argument being made that there are lots of them, which would put Anakin on his back foot in terms of battle tactics, but with their showings, I just find it hard to believe that they would be able to actually take him down, especially if they use the tactics that they showed against Kylo and Rey, where they mostly came out one at a time for a quick strike-and-away, I feel like he could thin their numbers pretty fast. He just seems like the superior combatant in every way. However, Anakin is again a master swordsman and capable of some insane force feats, such as pushing the groups to get them off of him, choking lone ones to easily kill them, or force-speeding around them to get the advantage. Other than their battle with Kylo and Rey, I'm unsure of any feats for them. It's the praetorian guard that I'm unsure about.

I have no doubt he can defeat the Knights with ease, the same as Ben did. Anakin, however, is repeatedly stated in the fiction to be amongst the greatest duelists of his age. First of all, the Knights of Ren get utterly thrashed by an armed Ben Solo, who to my knowledge is never specified to be an exceptional swordsman.
