Short answer: the JBL Partybox 520. It ranks #6 of 11 large party speakers by sound quality at $879.95; the Sony SRS-XV900 ranks #10 and costs $900, so there is not much of a tradeoff to weigh.
On the JBL Partybox 520 side: Handle and wheels are convenient. Set against that: Very large and heavy.
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 JBL Partybox 520. It ranks higher for sound quality than the Sony SRS-XV900 and costs less, so there is no real case for the other one.
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.
If battery life is a priority, the Sony SRS-XV900 is rated for 25 hours versus 15 hours for the JBL Partybox 520.
If water resistance matters to you, the JBL Partybox 520 at IPX4 (splashing) holds up far better than the Sony SRS-XV900 at no water resistance.
