Short answer: the Teufel Rockster. It ranks #7 of 11 large party speakers by sound quality; the Sony SRS-XV900 ranks #10.
What the Teufel Rockster offers: Loudest battery powered speaker. Watch for: Extremely heavy, not easy to carry.
What the Sony SRS-XV900 offers: Can get slightly louder than a Partybox 310. Watch for: Not as deep of bass and loses more bass at high volume compared to the Partybox 310 and every other speaker on this page
Buy the Teufel Rockster if sound quality matters more than the price. Buy the Sony SRS-XV900 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Sony SRS-XV900. It ranks near the bottom of the 11 large party speakers, so look higher up the list instead.
