He doesn't have the raw telekinesis feats, but this is where I think powerscaling and accolades win over that. Vader is afraid of Palpatine, while Caedus can at least somewhat contest Luke in close quarters. You'd also expect him to be more powerful given his age and likely superior potential - he's been training and fighting for perhaps longer.
Caedus certainly wins sabers - Caedus did better against angry peak Luke than Vader did against angry RotJ Luke (.i.e. Vader couldn't do shit), and I doubt rage! RotJ Luke > LotF Luke.
Force, I'd still say Caedus. He has lightning, he has shatterpoint to break his armor, he knows a variety of random ass Force powers, etc. He doesn't have the TK feats, but this may be from a lack of contexts or opportunities.
All-out goes to Caedus.
