Short answer: the KEF Muo gen2 on measured sound quality, the Bose SoundLink Color II on price. The KEF Muo gen2 ranks #73 of 136 medium speakers at $249.99. The Bose SoundLink Color II ranks #98 at $107.15, $142.84 cheaper.
What the KEF Muo gen2 offers: KEF seemed to have fixed the rolled off treble and overall balance Watch for: 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.
What the Bose SoundLink Color II offers: Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. IPX4 splashproof. Supports multipoint pairing to two devices at once. Watch for: Boosted bass on Color II. Not as deep of bass as other models. Lacking midrange detail. Rolled off treble
Buy the KEF Muo gen2 if sound quality is the priority over the price, or the Bose SoundLink Color II if the price is the priority over sound quality.
There is a real battery-life gap here: the KEF Muo gen2 is rated for 24 hours, the Bose SoundLink Color II only 8 hours.
Water resistance is not close: the KEF Muo gen2 is rated at IP67 (brief submersion), well ahead of the Bose SoundLink Color II at IPX4 (splashing).
