Short answer: the Sony SRS-XB43. It ranks #42 of 77 large speakers by sound quality at $150; the JBL Xtreme ranks #52 and costs $200, so there is not much of a tradeoff to weigh.
What the Sony SRS-XB43 gets right: Full, warm sound with deep, rich bass. The catch: Not as loud as others in the category.
The case for the JBL Xtreme: 15 hour battery. The tradeoff: Issues with bass distortion at high volumes.
Buy the Sony SRS-XB43. It ranks higher for sound quality than the JBL Xtreme and costs less, so there is no real case for the other one.
If battery life is a priority, the Sony SRS-XB43 is rated for 24 hours versus 15 hours for the JBL Xtreme.
