Short answer: the Minirig 4 if sound quality matters most, the Bogasing M5 if price matters most. The Minirig 4 ranks #7 of 177 medium speakers, rated 4.3/5, at $229.95. The Bogasing M5 ranks #61, rated 3.5/5, at $52.99, $176.96 cheaper.
The Minirig 4 is the better-sounding, louder pick. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. Alan Ross Reviews measured it at 106dB at full volume, against 96dB for the Bogasing M5. At 1.2 lbs (550 g) it weighs noticeably less than the Bogasing M5 at 1.7 lbs (757 g). The catch: Calls itself splash resistant and has no official water rating.
The Bogasing M5 is the tougher pick. A compact, backpack friendly speaker with very long battery life and USB-C charging at a budget price. It is rated IPX7 against Splash resistant for the Minirig 4. The catch: Front/rear driver configuration.
Buy the Minirig 4 if sound quality is the priority over the price, or the Bogasing M5 if the price is the priority over sound quality.
