Short answer: the Bose Soundlink Revolve+ II, and it is the safer pick. The JBL Flip 4 has less bass than a Flip 5 and costs $199 less, but our notes warn that battery failures are common. The Revolve+ II delivers true 360 sound that stays consistent wherever you stand, with overly boosted, warm bass as its main flaw.
Buy the Bose Soundlink Revolve+ II. It is rated higher for sound quality, and the JBL Flip 4 is discontinued, so it is only available used.
