Plagueis wasn't really good with a lightsabre. Not after he stopped practicing with them, of course.

You don't need to be told. Basically, watch every of Sidious' duel: He either lightsabres and constantly uses the Force or dominates his foes with the Force from the very beginning.
That's why he was also disarmed by Luke in Dark Empire. He also said something that Sith grew beyond the need of lightsabres and only use them in combat with Jedi to humiliate their heritage.

Sidious has numerous quotes proclaiming him as one of the best lightsaber duelists to have ever existed, and there's virtually nobody who can threaten his claim to the number 1. title aside from perhaps Luke Skywalker on his best day.
So no, none of that means what you want it to mean.

There's a strong argument to be made for Yoda since he apparently disarmed Sheev in some versions of the fight/off-screen. There's also the tight area on the senate podium which might have benefited Yoda. They're pretty much equals. Both masters of every style with flawless technique. Sheev perhaps slightly stronger in the Force circa RotS.
The description of Sheev's fighting style by Gillard and the description of his fight with the Maul brothers in Shadow Conspiracy really demonstrate how insane he is.
Also, Windu has some accolades proclaiming him equal to or even greater than Yoda and Sheev as a pure duelist, but also even more suggesting Yoda is his superior.
The main point is anyway, Sheev locked his lightsabers away to gather dust for over a decade and yet was able to match the likes of Windu and Yoda, who both maintained their skills rigorously, so I don't buy the argument Plagueis did anything but improve with his own skills.

in any case the difference in raw lightsaber skill among the few best ones is probably negligible, it comes down to force power tbh. like i doubt even the skill difference between maul and sidious is any more than marginal
Actually he isn't one of the best lightsabre duelists(anymore in his current versions) I think you talk about a TCW Insider where it is stated that he can use all lightsabre forms when fighting.
As about the Windu and Yoda duel. In the first, he was lightsabre-ly disarmed. Then, Anakin came and Sidious blasted Windu with Unlimited Power. In the second, Yoda was about to best him in lightsabre combat but he made use of his Telekinesis and Unlimited Power.
