i expect the palpatine and yoda's fight went by DBZ rules and we were viewing a high speed fight.Rebels is Disney though. Lucas force was a lot more restrained, Disney force does leans towards magic and superhero type powers.
Teleportation has been done before Disney it's not original. I suspect the force and lightsaber colours are whatever the writer/director feels like. There's pros and cons to that approach.
I say this because palps was far faster than windu in the windu fight. Yoda is faster than windu. Yet the fight between him and yoda looks slower at times. I say this is actually because the whole fight is slowed down. Palpatine is so fast the there is no cannon im aware of that ever even confirms someone close to him in speed. Yoda at young age would probably come closest. Physically palps biggest advantage was his speed.
