Which is more powerful the force or the magic from the harry potter universe?
Both are the very power of the universe, almost like what we might think of as God. The Force is more explicit about it (in the original trilogy) so I'd go with The Force.
On a Side note Harry Potter magic is closer to a mystical form of ethical humanism while The Force is pretty clearly the Tao.
Force may be stronger but magic is more useful. Magic it is more practical and people would believe it more than the force. Force can be considered psychic powers or magic to those who don't believe it. If they fight beings of chaos they are screwed.
@JediXMan: I'd much prefer to have all these powers and abilities than harry potter magic.
Also until Harry potter does something like in the scan you showed will I be impressed by them.
(I'm agreeing with you)
