honestly, i think Vader can solo both. He might not be more powerful than her, but he is by far the better warrior, much more skilled, much more durable, better stamina, and she aint getting even close to fully overpowering him with the force if sheev couldnt.

Why would Vader's skill, stamina and durability be a factor against Talzin's magic?

Team.
