Agreed. The Nexus is somewhat equivalent to the SII performance wise with a few changes here and there. It would only make sense to get the S3.
I'm sure there will also be a sizable rooting and ROM community just like the SII which will allow it to get Jelly Bean even sooner and even stock if you dislike TouchWiz (I think that's what Samsung uses).
