Short answer: the Soundcore 2. It ranks #106 of 175 medium speakers by sound quality, rated 3.0/5, at $29.99; the Ultimate Ears Megaboom 4 ranks #170, rated 2.1/5, and costs $200, so there is little reason to consider the other one.
The Soundcore 2 is the better-sounding, lighter pick. At 0.7 lbs (318 g) it weighs much less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It keeps a wired aux input, which the Ultimate Ears Megaboom 4 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Megaboom 4.
Why pick the Ultimate Ears Megaboom 4: IP67 rated, floats, and finally uses USB-C charging. It has an adjustable EQ, which the Soundcore 2 lacks. It charges over USB-C rather than Micro USB. The tradeoff: A lot of distortion at higher volumes.
Buy the Soundcore 2. It is rated higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, which makes it the one to get unless you need something the other one does better.

Newer model: the Soundcore 3, ranked higher, rated 3.4/5, released Jan 2021. It adds app control and adjustable EQ, but drops the aux input. See every Soundcore 2 and 3 generation.
Pros: Soundcore 2 uses 2x 38mm fullrange. Its 318 g, claimed 24 hours (Manufacturer specified) battery life, IPX7 protection, aux input and stereo playback make it a practical option for its intended room or portable use.
Cons: Its 70Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment.
