Short answer: the Bose Soundlink Flex. It ranks #36 of 150 medium speakers by sound quality, rated 3.8/5, at $79.99; the Tribit Stormbox Pro ranks #43, rated 3.7/5, and costs $90, so there is not much of a tradeoff to weigh.
What the Bose Soundlink Flex does well: IP67 rated; rugged enough to survive drops from several feet and floats. The catch: Not stereo.
The case for the Tribit Stormbox Pro: 24 hour battery life (60% volume, XBass off); doubles as a power bank. Watch for: Bottom woofer was fixed in a later firmware, upgrade for best sound.
One note: the Tribit Stormbox Pro is no longer sold new, but at #43 of 150 medium speakers by sound quality it still outranks most current models, so used is worth considering.
Buy the Bose Soundlink Flex. It is rated higher for sound quality than the Tribit Stormbox Pro and costs less, which makes it the one to get unless you need something the other one does better.
Battery life favors the Tribit Stormbox Pro: rated for 24 hours against 12 hours for the Bose Soundlink Flex.

Tribit Stormbox Pro: $90 Discontinued eBay
Newer model: the Tribit Stormbox Max. It’s likely to perform similarly, though we can’t confirm that yet.
Pros: 24 hour battery life (60% volume, XBass off); doubles as a power bank. IP67 rated. Multi-point Bluetooth 5.3 pairing. Measured bass extension of 58Hz (-10dB).
Cons: Bottom woofer was fixed in a later firmware, upgrade for best sound. Peaky mids, highs rolled off. Not technically a 360 speaker, only front and rear. Discontinued; Tribit has retired it.
