Short answer: the KEF Muo gen2 on sound, the Tribit Stormbox Mini+ on features. The Stormbox Mini+ packs IPX7 waterproofing, app support with EQ presets and AAC, true wireless stereo, USB-C charging and a built-in mic for calls, but it is not a great sounding speaker with really weak bass. The Muo gen2 is the better-balanced option, though it too lacks deeper bass.
Buy the KEF Muo gen2 if sound quality matters more than the price. Buy the Tribit Stormbox Mini+ if the price matters more than sound quality.
Battery life favors the KEF Muo gen2: rated for 24 hours against 12 hours for the Tribit Stormbox Mini+.
