I don't think DE Sidious is any better in sabers than RotJ, just force.
And two on one makes things very hard, especially against ones of this level.

The twins take sabers only in a difficult fight. The other ones, I could see Sidious removing Jaina with the Force to dispose of Caedus.
Her force defense is pretty good, though, she was able to block all of what Caedus was throwing.
Even if she was temporarily knocked away, Caedus can definitely hold til she rejoins. And actually taking her out with force would take a lot of effort even for Sidious, an amount of effort I don't think he can spare with Caedus around.
