Short answer: the Harman Kardon Luna. It ranks #26 of 175 medium speakers by sound quality (rated 4.0/5) at $290.99 and is still sold new; the Soundcore Glow ranks #50 (rated 3.6/5) and is discontinued, so it is only an option used.
The Harman Kardon Luna is the better-sounding pick. The sound is fairly balanced apart from the boosted bass. The tradeoff: Boosted bass, and less detailed than higher-ranked speakers.
The Soundcore Glow is the longer-running, lighter choice. Nice light show. It is rated for 18 hours of battery against 12 for the Harman Kardon Luna. At 1.8 lbs (800 g) it weighs noticeably less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It supports AAC Bluetooth, which the Harman Kardon Luna lacks. The tradeoff: Bass falls off quickly at louder volumes, leaving mostly treble; distortion on bass-heavy tracks at full volume.
Buy the Harman Kardon Luna. It is rated higher for sound quality and still sold new, while the Soundcore Glow is discontinued.

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.
