Short answer: the Ultimate Ears Wonderboom 4, though neither ranks well in its class. It ranks #89 of 144 medium speakers by sound quality, rated 2.9/5, at $59.99; the Skullcandy Terrain XL ranks #134, rated 2.1/5, and costs $79.99, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 144 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
What the Ultimate Ears Wonderboom 4 does well: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the Skullcandy Terrain XL does well: The loudest and longest-running of the Terrain line at 95dB and 18 hours, and the only one with a built-in microphone. Watch for: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble.
Buy the Ultimate Ears Wonderboom 4. It is rated higher for sound quality than the Skullcandy Terrain XL and costs less, which makes it the one to get unless you need something the other one does better.

Skullcandy Terrain XL: $79.99 Amazon eBay
Pros: The loudest and longest-running of the Terrain line at 95dB and 18 hours, and the only one with a built-in microphone. IPX7 rated with a nylon wrist wrap. Multi-Link pairs it with other Skullcandy speakers.
Cons: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble. The extra size buys volume and runtime, not better sound.
