Short answer: the JBL Charge Essential 3 SE. It ranks #40 of 150 medium speakers by sound quality, rated 3.7/5, at $199.95; the KEF Muo gen2 ranks #83, rated 3.1/5, and costs $249.99, so there is not much of a tradeoff to weigh.
What the JBL Charge Essential 3 SE does well: Gets louder than the Bose SoundLink Flex 2nd Gen and digs deeper in the bass, with a separate 20mm tweeter, two passive radiators and 40W of amplification in the familiar Charge body. Watch for: In side-by-side listening against the Charge 6, its bass is weaker and less stable and distorts on bass-heavy tracks even with the bass turned down in the app, while a narrow boost in the upper mids makes it sound less natural.
The case for the KEF Muo gen2: KEF seemed to have fixed the rolled off treble and overall balance. The catch: Lacking deeper bass.
Buy the JBL Charge Essential 3 SE. It is rated higher for sound quality than the KEF Muo gen2 and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
JBL Charge Essential 3 SE: $199.95 JBL eBay
Older models: the JBL Charge Essential 2 (ranked higher, rated 3.8/5) and the JBL Charge Essential (ranked lower, rated 3.2/5).
Pros: Gets louder than the Bose SoundLink Flex 2nd Gen and digs deeper in the bass, with a separate 20mm tweeter, two passive radiators and 40W of amplification in the familiar Charge body. IP67 water and dust protection, a claimed 20 hours of battery life, a USB-C power bank output, Auracast stereo pairing and multi-speaker linking, Bluetooth 5.4 with AAC, and app EQ.
Cons: In side-by-side listening against the Charge 6, its bass is weaker and less stable and distorts on bass-heavy tracks even with the bass turned down in the app, while a narrow boost in the upper mids makes it sound less natural. Against the Bose SoundLink Flex 2nd Gen it sounds muddier and more strident, with less detail and a smaller soundstage. At full price it costs as much as the Charge 6, which is the better speaker.

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.
