Short answer: the JBL Partybox 310 for bass, the Teufel Rockster Air 2 for off-axis consistency. The Teufel’s horn-loaded compression driver stays more consistent off-axis than the JBL Partybox 130, though its bass is not as deep as that JBL’s boosted low end, which the source calls boomy, not deep. The 310 has the deepest bass of any battery powered speaker, though it is large and its daisychain will not work with non-JBL speakers.
Buy the JBL Partybox 310 ($449.95) for a party speaker; the Teufel Rockster Air 2 ($599.99) suits a battery-powered PA speaker instead.
There is a real battery-life gap here: the Teufel Rockster Air 2 is rated for 58 hours, the JBL Partybox 310 only 18 hours.
Water resistance is not close: the JBL Partybox 310 is rated at IPX4 (splashing), well ahead of the Teufel Rockster Air 2 at no water resistance.

Newer model: the JBL Partybox 330, ranked higher, rated 4.6/5.

Cons: Very large. Discontinued.

Teufel Rockster Air 2: $599.99 Amazon eBay
Older model: the Teufel Rockster Air (ranked lower, rated 3.4/5).
Pros: More consistent off-axis sound than the JBL Partybox 130, thanks to its single horn-loaded compression driver. Projects sound more evenly to the sides, unlike the JBL’s narrower front-firing dispersion. Cleaner instrument separation at high volume than the JBL Partybox 130, which turns anemic and loses bass at max volume despite its bass boost.
Cons: Bass isn’t as deep as the JBL Partybox 130’s boosted bass, though the JBL’s is boomy rather than truly deep. Bass and treble aren’t perfectly controlled at maximum volume: can sound hollow or too bright unless turned down from default. Not meaningfully louder than its 3-year-old predecessor, and the reviewer found the overall tuning a bit worse.
