Vader had several notable advantages in the fight yes but that doesn't explain the complete turn around in his performance despite there only being around half a year in time between TFU I and TFU II.
Nah. Starkiller's feats are about on par with Galen's higher end TK and his performance against Sidious puts him firmly above.
