Exactly. While starting NJO Luke should be better, Anakin is not the best/most powerful at the time of RotS. Of *his* generation, sure... but he's of a different generation to Obi-Wan, Mace and *certainly* Yoda. He feels the Force more strongly than any other Jedi - this is true, but to put it in the same words Obi-Wan used to Luke, he 'cannot control it' to the same extent as someone like Yoda, Mace or Sidious. The very fact that he is equal to Obi-Wan Kenobi, third greatest living Jedi in the entire Order after he's had thirteen years of training to Obi's near forty, is all the testament to his power there needs to be. If Anakin was on Mace or Yoda levels however, he'd not only have *demolished* Obi-Wan on Mustafar, we'd have seen evidence of his Force abilities overwhelming Obi's. The fact that they produced a Force push of equal intensity was to highlight the fact that they were completely and totally equally matched - both in Force and blade ability. Cyborg Vader is more powerful than RotS Anakin. You think he was just blowing hot air when he told Obi-Wan that he was the master now? Why would he keep waxing lyrical about the power of the dark side unless he'd increased in strength? He's lost a lot of his former potential (60% of it in fact), but RotS Anakin had barely scratched the surface of that potential, so he still had a fair bit to climb until he was at the "80% of the Emperor" that he supposedly is. Your guitar comparison was very apt. In this context, your teacher is a Mace/Yoda and you're a Skywalker. Sure, Anakin's more talented than they are, but they have the greater mastery over the Force and would still hand him his ass... he's the best/greatest Jedi Knight (in that he's more powerful than most of the masters). The greatest amongst the masters, however, would defeat him. Had he been given another couple of years of war however, who knows?
