Short answer: the Sony SRS-XV500, if you are buying new. The JBL Partybox 300 ranks higher than it (#10 vs #16 of 44 party speakers, 4.3/5 vs 4.0/5) but is discontinued, so only consider it used; the Sony SRS-XV500 is still sold new at $315.
What the JBL Partybox 300 does well: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. The catch: Hard to carry, too tall, drags on the ground.
The Sony SRS-XV500 is the longer-running, lighter pick. RTINGS measured a slightly warm sound with plenty of bass punch, and found it gets very loud for outdoor parties. It is rated for 25 hours of battery against 18 for the JBL Partybox 300. At 24.7 lbs (11.2 kg) it weighs noticeably less than the JBL Partybox 300 at 35.3 lbs (16 kg). It is rated IPX4, while the JBL Partybox 300 has no water resistance. The tradeoff: RTINGS measured poor directivity, so the sound changes noticeably as you move off to the sides.
Buy the Sony SRS-XV500 new; the JBL Partybox 300 is no longer sold new, so it only makes sense as a used find.

Sony SRS-XV500: $315.00 Amazon eBay
Older model: the Sony SRS-XP500 (ranked higher, 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.
