Which surround sound system - HELP please!!!

[Wilks]

Which system should I go for folks. I have a 40" Samsung LCD, Sky+ HD, and a Playstation 3 to plug in. I'm looking for whichever system would provide me the best sound quality out of the following:

ONKYO HT-S3305B 3D-Ready 5.1Ch AV Receiver with Speakers

and

LG HB905PA 5.1 Blu-ray Hybrid Home Cinema

Please help!
