Short answer: the Sony ULT Field 3, since the Tribit Stormbox Mini+ is called not a great sounding speaker. The Tribit offers IPX7, app EQ presets, AAC, TWS pairing, USB-C and a mic at $39.99, but its bass is really weak. The Sony is IP67 rated and dustproof and water resistant at $208, yet it sounds a bit hollow with boosted treble.
Buy the Sony ULT Field 3 when sound quality outweighs the price for you, and the Tribit Stormbox Mini+ when the price outweighs sound quality instead.
Battery life favors the Sony ULT Field 3: rated for 24 hours against 12 hours for the Tribit Stormbox Mini+.
