Force wise they're still around even in canon. Yoda may be more powerful though since though he was over matched by Sidious, Vader also was in Lords of the Sith and it is hinted that Sidious wasn't using his full power.
Skill wise Yoda is still Vader's better by feats.
Speed wise I'm not sure. Vader has created 13 afterimages with blade whilst blocking omnidirectional fire.
Strength and endurance is debatable.
Durability goes to Vader.
Yoda is obvious more knowledgeable/versatile in the force and Darth Vader's mobility is hampered by his suit.
Probably still Yoda but a good fight nonetheless.
