Short answer: the JBL Partybox Stage 320. It ranks #3 of 40 party speakers by sound quality, rated 4.6/5, at $499.95. The Sony SRS-XV500 ranks #15, rated 4.0/5, at $310, $189.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the JBL Partybox Stage 320: Handle and wheels are convenient. The tradeoff: Slightly sibilant in the treble at full blast.
What the Sony SRS-XV500 does well: RTINGS measured a slightly warm sound with plenty of bass punch, and found it gets very loud for outdoor parties. Watch for: RTINGS measured poor directivity, so the sound changes noticeably as you move off to the sides.
Buy the JBL Partybox Stage 320. It is rated higher for sound quality, and the $189.95 you would save on the Sony SRS-XV500 does not close the gap.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.

Sony SRS-XV500: $310.00 Amazon eBay
Older model: the Sony SRS-XP500 (rated 4/5).
Pros: RTINGS measured a slightly warm sound with plenty of bass punch, and found it gets very loud for outdoor parties. Two 140mm woofers and two 60mm tweeters in a bass reflex cabinet, with a claimed 25 hours of battery life and a 10 minute quick charge for about 2.5 hours of play. Two 6.3mm inputs switch between microphone and guitar, with karaoke controls for key, echo and per-input volume, plus a 3.5mm aux input. IPX4 splash resistance and built-in lighting.
Cons: RTINGS measured poor directivity, so the sound changes noticeably as you move off to the sides. Bass compresses and pumps as you approach maximum volume. At 11.2 kg it is heavy to carry, and IPX4 only covers splashes.
