Short answer: the Bose Soundlink Flex for the higher ranking, the Tribit Stormbox Flow for the lower price. The Bose Soundlink Flex ranks #34 of 134 medium speakers at $89. The Tribit Stormbox Flow ranks #49 at $60, $29 cheaper.
On the Bose Soundlink Flex side: IP67 rated. The tradeoff: Warm sounding with overly boosted bass which drowns out midrange detail.
The case for the Tribit Stormbox Flow: Up to 30 hours of battery life - roughly double most rivals (~20-24 hrs with XBass on). Set against that: Midrange and bass are weirdly recessed about 4db below 700hz.
Buy the Bose Soundlink Flex if the ranking matters more than the price. Buy the Tribit Stormbox Flow if the price matters more than the ranking.

Tribit Stormbox Flow: $60 Amazon
Pros: Up to 30 hours of battery life - roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too.
Cons: Not stereo. Midrange and bass are weirdly recessed about 4db below 700hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.
