Short answer: the Soundcore Motion 300, if you are buying new. The Soundcore Motion+ ranks higher than the Minirig 4 (#4 vs #7 of 179 medium speakers) but is discontinued; its replacement, the Soundcore Motion 300, is rated 4.5/5 at $79.99 and is still sold new.
Minirig 4 is modular, with an optional subwoofer attachment and orientation-aware sound over USB-C charging, though it’s only rated splash resistant rather than carrying an official IP rating, and our notes flag it as having more reported reliability issues than any other speaker on this site.
Motion+ pairs separate tweeters with bigger woofers for more bass at full volume and better off-axis treble per our notes, but Soundcore has discontinued it and it needs a community EQ profile to sound its best.
Buy the Minirig 4 if you want a currently-sold speaker with a modular subwoofer option and can live with its known reliability complaints. Buy the Motion+ only if you find old stock cheap and are willing to install a community EQ.
There is a real battery-life gap here: the Minirig 4 is rated for 30 hours, the Soundcore Motion+ only 12 hours.
If water resistance matters to you, the Soundcore Motion+ at IPX7 (brief submersion) holds up far better than the Minirig 4 at Splash resistant (splashing).
