Short answer: the Xiaomi Sound Outdoor, if you are buying new. The Minirig 2 ranks higher than it (#9 vs #47 of 164 medium speakers, 4.3/5 vs 3.7/5) but is discontinued, so only consider it used; the Xiaomi Sound Outdoor is still sold new at $54.99.
The Minirig 2 is the better-sounding, longer-running pick. Modular, can easily attach a subwoofer. It is rated for 40 hours of battery against 12 for the Xiaomi Sound Outdoor. It keeps a wired aux input, which the Xiaomi Sound Outdoor lacks. It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. Watch for: Calls itself splash resistant and has no official water rating.
The Xiaomi Sound Outdoor is the tougher pick. A decent sounding speaker for its size. It is rated IP67 against Splash resistant for the Minirig 2. The catch: Boosted bass that gets somewhat uncontrolled at high levels.
Buy the Xiaomi Sound Outdoor new; the Minirig 2 is no longer sold new, so it only makes sense as a used find.

Xiaomi Sound Outdoor: $54.99 Amazon eBay
Pros: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. A decent sounding speaker for its size.
Cons: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment. Boosted bass that gets somewhat uncontrolled at high levels.
