[Star Wars: ROTS] Was Anakin post-Dark Side turn and pre-Mustafar accident a contender to kill Palpatine had he wished to do so?

Ok, hear me out. There was a the movie-licensed game on the PS2 of Revenge of the Sith, where there was an "alternate" ending of Anakin killing Obi Wan during the final blow as opposed to getting maimed. Anyways, Palpatine shows up as usual, and Anakin basically kills him as well, a shock no doubt to Palps, and proclaims himself the new emperor of the Galaxy.

It was just a fun "what-if" the developers had put in I guess.

But my question is, is there truth to this act? Was Anakin (Darth Vader) before injury much stronger than Palpatine? We know that he is the chosen one, and possibly one of the strongest Jedi at this point. Was there any reason for Palpatine to fear him?

No. Anakin had the potential at that time to become more powerful than the emperor, but he was arrogant of his abilities as the Chosen One. It is stated and shown numerous times in both legends and canon that Vader would grow stronger than he was as Anakin, but was never close to being able to beat Palpatine in a direct confrontation.
