Short answer: the Bose Soundlink Mini 2 is the better-built speaker; the Charge 4 is the power bank. The Bose has a compact aluminum build that feels sturdy and dense, but its upper bass is boosted like most Bose speakers. The Charge 4 doubles as a power bank for charging phones and tablets, though it is not stereo.
Buy the JBL Charge 4 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Earfun Uboom L instead.
Water resistance is not close: the JBL Charge 4 is rated at IPX7 (brief submersion), well ahead of the Bose Soundlink Mini 2 at no water resistance.
