Short answer: the Skullcandy Terrain XL, though neither ranks well in its class. Both are rated 2.1/5 for sound quality (#168 and #173 of 179 medium speakers), and the Skullcandy Terrain XL costs $79.99 against $200 for the Ultimate Ears Megaboom 4, and with sound quality even, the cheaper one is the better buy. Both are rated below 3.0/5 among the 179 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Skullcandy Terrain XL is the lighter option. A very loud, long running Terrain speaker, waterproof with a wrist wrap and a built in microphone. At 1.4 lbs (635 g) it weighs much less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). The tradeoff: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble.
Why pick the Ultimate Ears Megaboom 4: A tough waterproof speaker that floats, with USB-C charging, a long battery and PartyUp linking. It has an adjustable EQ, which the Skullcandy Terrain XL lacks. The catch: A lot of distortion at higher volumes.
Buy the Skullcandy Terrain XL. Both are rated the same for sound quality, and it costs $120.01 less than the Ultimate Ears Megaboom 4.
