Short answer: the Vifa Helsinki for midrange and treble, the Tribit Stormbox Lava for bass and easy setup. The Helsinki is generally regarded as having the best midrange and treble of any battery powered Bluetooth speaker, but it has no TWS pairing and needs a hacked Android app to enable night mode. The Lava has fantastic bass extension, though it is quite heavy for the size.
Buy the Tribit Stormbox Lava new; the Vifa Helsinki is no longer sold new, so it only makes sense as a used find.
Battery life favors the Tribit Stormbox Lava: rated for 24 hours against 8 hours for the Vifa Helsinki.
There is a real gap in water resistance: the Tribit Stormbox Lava at IP67 (brief submersion) against the Vifa Helsinki, which has no water resistance.

A loud, waterproof large speaker with strong bass, a long battery and an aux input, for far less than its rivals.
A superb sounding battery powered speaker, with exceptionally clean mids and treble, now discontinued but worth buying used.
