Short answer: the KEF Muo gen2. It ranks #97 of 175 medium speakers by sound quality (rated 3.1/5) at $249.99 and is still sold new; the Bose SoundLink Color II ranks #125 (rated 2.7/5) and is discontinued, so it is only an option used.
The KEF Muo gen2 is the better-sounding, longer-running choice. KEF seemed to have fixed the rolled off treble and overall balance. It is rated for 24 hours of battery against 8 for the Bose SoundLink Color II. It is rated IP67 against IPX4 for the Bose SoundLink Color II. It supports aptX Adaptive Bluetooth, which the Bose SoundLink Color II lacks. Watch for: Lacking deeper bass.
The case for the Bose SoundLink Color II: Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. Watch for: Boosted bass on Color II.
Buy the KEF Muo gen2. It is rated higher for sound quality and still sold new, while the Bose SoundLink Color II is discontinued.

The Two Speakers In Full
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.
