Short answer: the Tribit Stormbox Flow for battery life, the Bose Soundlink Flex for durability. The Flow runs up to 30 hours, roughly double most rivals and about 20 to 24 hours with XBass on, but its midrange and bass are weirdly recessed about 4db below 700Hz. The Flex is IP67 rated, though its warm sound with overly boosted bass drowns out midrange detail.
Buy the Bose Soundlink Flex. It is rated higher for sound quality than the Tribit Stormbox Flow at the same price, so it is the default pick unless a specific strength of the other one matters more to you.
There is a real battery-life gap here: the Tribit Stormbox Flow is rated for 30 hours, the Bose Soundlink Flex only 12 hours.
