Short answer: the Harman Kardon Luna if sound quality matters most, the Soundcore Glow if price matters most. The Harman Kardon Luna ranks #22 of 136 medium speakers at $290.99. The Soundcore Glow ranks #43 at $80, $210.99 cheaper.
What the Harman Kardon Luna offers: Pretty balanced sound besides the boosted bass. Watch for: Not stereo. Boosted bass, not as detailed as higher ranked speakers
What the Soundcore Glow offers: Nice light show. Treble boosted 7db. Not technically a 360 speaker, only front and rear. Watch for: 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.
