Pioneer VSX-932 or VSX-933?

I'm looking to assemble a 5.1.2 home theater system for the TV using the following speakers:

FL & FR (with top firing for Atmos):

Pioneer SP-BS22A-LR http://www.pioneerelectronics.ca/POCEN/Home/Speakers/Pioneer+Speakers/SP-BS22A-LR

Center: Pioneer SP-C22 http://www.pioneerelectronics.ca/POCEN/Home/Speakers/Pioneer+Speakers/SP-C22

RL & RR: Pioneer SP-BS22-LR http://www.pioneerelectronics.ca/POCEN/Home/Speakers/Pioneer+Speakers/SP-BS22-LR

I'm having trouble deciding between the VSX-932 ($349 on Amazon Canada) and the VSX-933 ($720 Amazon Canada). More than 2x the cost but for what benefit? None that I can see unless anyone can offer some insight or alternatives.

Edit:

My TV is a Sony XBR55X800E and I want to use the setup for the TV’s apps, an Xbox One X, and possibly a media center PC in the future.
