Short answer: the Bose Soundlink Flex. It ranks #38 of 182 medium speakers by sound quality, rated 3.8/5, at $79.99. The Skullcandy Terrain ranks #172, rated 2.1/5, at $49.93, $30.06 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Bose Soundlink Flex is the better-sounding option. A small, rugged waterproof speaker that survives drops and floats, with a warm, bass forward sound for casual outdoor use. Watch for: Warm sounding with overly boosted bass which drowns out midrange detail.
The Skullcandy Terrain is the lighter option. A waterproof speaker with a wrist wrap for carrying and pairing with other Skullcandy speakers. At 1 lbs (458 g) it weighs noticeably less than the Bose Soundlink Flex at 1.3 lbs (589 g). The catch: No bass, very rolled off treble.
Buy the Bose Soundlink Flex. It is rated higher for sound quality, and the $30.06 you would save on the Skullcandy Terrain does not close the gap.
