Short answer: the Ultimate Ears Megaboom 4, if you are buying new. The Soundcore Glow ranks higher than it (#50 vs #170 of 175 medium speakers, 3.6/5 vs 2.1/5) but is discontinued, so only consider it used; the Ultimate Ears Megaboom 4 is still sold new at $200.
The Soundcore Glow is the better-sounding, lighter choice. Nice light show. At 1.8 lbs (800 g) it weighs noticeably less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It supports AAC Bluetooth, which the Ultimate Ears Megaboom 4 lacks. The tradeoff: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume.
Why pick the Ultimate Ears Megaboom 4: IP67 rated, floats, and finally uses USB-C charging. The tradeoff: A lot of distortion at higher volumes.
Buy the Ultimate Ears Megaboom 4 if you want one new; the Soundcore Glow is discontinued, so only look for it used.

The Two Speakers In Full
Soundcore Glow: $80 Discontinued eBay
Pros: Nice light show. Treble boosted 7db. Not technically a 360 speaker, only front and rear. Measured bass extension of 54Hz (-10dB).
Cons: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume. Light effects and bass-boost noticeably shorten battery life. USB-C port doesn’t support power-bank charging. Discontinued and no longer sold new.
