Palps easily wins all he bested Yoda who was a Jedi grandmaster and manages to manipulate all the Jedi as well as the chosen one Palps truly is the winner
Unfortunately we don't know too much about full power Anakin, apart from George Lucas stating he would've been 200% of Sidious' full power, whilst he only reached 80% as Vader
George was pressed in an interview and said anakin and Luke were equal in power, anakin was the one who failed and luke was the one who succeeded to achieve his full power, although in legends his death isn't really something I can recall so who knows how powerful he got
