Short answer: the Sony SRS-XV900 for raw loudness, the JBL Partybox 310 for bass. The Sony can get slightly louder than the 310 and also has a convenient handle and wheels, but its bass is not as deep and it loses more bass at high volume than the 310 and every other speaker on the page. The 310 has the deepest bass of any battery powered speaker and the most balanced sound in its class, though it is very large.
On the JBL Partybox 310 side: Absolute deepest bass of any battery powered speaker, most balanced sound in the class, handle and wheels are convenient. The tradeoff: Very large.
