Short answer: the Minirig 4 with subwoofer, if you are buying new. The Minirig 3 with subwoofer ranks higher than the Bose SoundLink Plus (#6 vs #25 of 120 large speakers) but is discontinued; its replacement, the Minirig 4 with subwoofer, is rated 4.6/5 at $290 and is still sold new.
The Minirig 3 with subwoofer is the better-sounding, longer-running pick. A compact speaker and subwoofer pair with very balanced sound and a long battery, now discontinued but worth buying used. It is rated for 30 hours of battery against 20 for the Bose SoundLink Plus. It keeps a wired aux input, which the Bose SoundLink Plus lacks. It has an adjustable EQ, which the Bose SoundLink Plus lacks. The catch: Not stereo, app is buggy.
The Bose SoundLink Plus is the tougher option. A waterproof mid size speaker with vibrant sound, booming bass, clean mids, a long battery and premium build. It is rated IP67 against Splash resistant for the Minirig 3 with subwoofer. It links with other speakers (Bose Party mode), which the Minirig 3 with subwoofer cannot. It plays in stereo from a single unit, unlike the Minirig 3 with subwoofer. The tradeoff: Boosted thuddy bass, but not as deep as the SoundLink Flex and you should probably just buy one of those instead if you want a Bose.
Buy the Minirig 4 with subwoofer, the replacement for the discontinued Minirig 3 with subwoofer; it is rated higher for sound quality than the Bose SoundLink Plus.
