Short answer: the Soundcore Motion 300 for deep bass in a small speaker, the Minirig 4 for modularity. The Motion 300 gets pretty deep bass for its small size, but it needs the above EQ work or its top two treble EQ bars at max. The Minirig 4 is modular and can easily attach a subwoofer, though it calls itself splash resistant with no official water rating.
Buy the Soundcore Motion 300. It is rated higher for sound quality than the Minirig 4 and costs less, which makes it the one to get unless you need something the other one does better.
There is a real battery-life gap here: the Minirig 4 is rated for 30 hours, the Soundcore Motion 300 only 13 hours.
Water resistance is not close: the Soundcore Motion 300 is rated at IPX7 (brief submersion), well ahead of the Minirig 4 at Splash resistant (splashing).
