Short answer: the Flip 6 is more neutral and smaller; the SoundLink Flex is the floating, drop-resistant alternative. Bose is #38 of 179, while JBL is #13 of 179.
Flex is IP67 rated and floats, but its boosted bass can mask midrange detail. It is the utility-first choice rather than the most accurate speaker.
Flip 6 is a 1.2 lbs (544 g) neutral 30W speaker with a 56Hz bass specification and 98dB maximum output. It is mono and has less claimed battery life, but it is the better fit for music listening.
Buy the Bose SoundLink Flex at $79.99 if floating ruggedness matters most.
Buy the JBL Flip 6 at $79.95 if clear, balanced sound in a smaller speaker matters more.
