Onkyo rz830 vs pioneer vsxlx503

Anyone have experience with either of these receivers? Newegg has these for $650 (pioneer) and $700 (onkyo). Of course they are actually more up front, but both come with gift cards, which I would use for other networking components. I’m looking for a 9.2 receiver with three zones and these seem to be pretty good options for the money. Onkyo has a higher list price, and is thx certified, but pioneer seems to have slightly higher ratings.

Any insight is appreciated.
