Short answer: the Harman Kardon Luna 2 on rank, the JBL Charge 5 on battery and charging. The Luna 2 places #25 of 172 against #30 of 172 with an articulate, spacious midrange and tight bass from its 62mm x 82mm woofer. The Charge 5 runs about 20 hours, survives a 1m dunk for 30 minutes and doubles as a power bank, but it is not stereo and its upper mids are shouty.
Buy the Harman Kardon Luna 2 when sound quality outweighs the price for you, and the JBL Charge 5 when the price outweighs sound quality instead.
