Short answer: the JBL Partybox Stage 320 on ranking, the Sony SRS-XP500 on battery. The XP500 offers a 20W 3-way system with dual passive radiators and 20-hour battery life, but it is not as loud and its bass is not as deep as a Partybox 100 or 110. The Stage 320 ranks #3 of 44 against #15 of 44 at $499.95 against $549.99, though it is very large and slightly sibilant in the treble at full blast.
Buy the JBL Partybox Stage 320. It is rated higher for sound quality, and the Sony SRS-XP500 is discontinued, so it is only available used.
There is a real gap in water resistance: the JBL Partybox Stage 320 at IPX4 (splashing) against the Sony SRS-XP500, which has no water resistance.
