Short answer: the Tribit Stormbox Lava. It ranks #3 of 105 large speakers by sound quality, rated 4.6/5, at $119.99; the Ultimate Ears Epicboom ranks #83, rated 2.9/5, and costs $228.59, so there is little reason to consider the other one.
The Tribit Stormbox Lava is the better-sounding, deeper-bass choice. A powerful, IP67-rated portable speaker with a measured 44Hz -10dB bass point, 10-band app EQ, aux input and 24-hour claimed battery life. Its bass reaches about 44Hz before falling 10dB, against 55Hz for the Ultimate Ears Epicboom. It is rated for 24 hours of battery against 17 for the Ultimate Ears Epicboom. It supports AAC Bluetooth, which the Ultimate Ears Epicboom lacks. Watch for: XBass can make the low end muddy and obscure vocals, while the deepest notes lose authority and clarity falls at maximum volume.
The case for the Ultimate Ears Epicboom: 17 hour battery with USB-C charging (first UE portable with USB-C). The catch: Not very deep bass for the size.
Buy the Tribit Stormbox Lava. It is rated higher for sound quality than the Ultimate Ears Epicboom and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Pros: A powerful, IP67-rated portable speaker with a measured 44Hz -10dB bass point, 10-band app EQ, aux input and 24-hour claimed battery life. Independent reviews find that it gets loud with impactful bass, and careful EQ or current firmware can produce relatively clean sound through the mids and highs. Measured bass extension of 44Hz (-10dB).
Cons: XBass can make the low end muddy and obscure vocals, while the deepest notes lose authority and clarity falls at maximum volume. It is heavy for its size, its front-facing design has a narrow soundstage, and one review noted a brief sound interruption while changing volume.
Setup: Update the firmware to version 2 or later first, since version 2 was a big step up in sound quality. Then try out the Alan Ross EQ’s at this timestamp in his video. There’s also a max bass EQ from Oluv and you can turn down the lowest slider for it to be more neutral.
