Short answer: the KEF Muo gen2, if you are buying new. The Bose Soundlink Mini 2 ranks higher than it (#72 vs #97 of 175 medium speakers, 3.4/5 vs 3.1/5) but is discontinued, so only consider it used; the KEF Muo gen2 is still sold new at $249.99.
Why pick the Bose Soundlink Mini 2: Compact aluminum build feels sturdy and dense. ~10 hour battery life; can pair to two devices at once and remembers up to 8. It keeps a wired aux input, which the KEF Muo gen2 lacks. The tradeoff: Boosted upper bass like most Bose speakers.
The KEF Muo gen2 is the longer-running, tougher option. KEF seemed to have fixed the rolled off treble and overall balance. It is rated for 24 hours of battery against 10 for the Bose Soundlink Mini 2. It is rated IP67, while the Bose Soundlink Mini 2 has no water resistance. It supports aptX Adaptive Bluetooth, which the Bose Soundlink Mini 2 lacks. The catch: Lacking deeper bass.
Buy the KEF Muo gen2 if you want one new; the Bose Soundlink Mini 2 is discontinued, so only look for it used.

KEF Muo gen2: $249.99 Amazon $249.99 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.
