Short answer: the KEF Muo gen2 sounds more balanced; the Charge 2 is the power bank. KEF seemed to have fixed the rolled off treble and overall balance on the Muo gen2, but it is still lacking deeper bass. The Charge 2’s bass compresses at higher volumes, so pick it only for the 6000mAh power bank.
Buy the KEF Muo gen2 if you want one new; the JBL Charge 2 is discontinued, so only look for it used.

KEF Muo gen2: $249.99 Amazon eBay
Pros: KEF seemed to have fixed the rolled off treble and overall balance
Cons: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
