Short answer: the Minirig 3 with subwoofer on price, the Vifa Oslo on treble detail. The Minirig is very balanced and costs $289 less, though it is not stereo and the app is buggy. The Oslo delivers extreme treble detail with decent bass, but a dip at 270Hz colors its response.
Buy the Minirig 3 with subwoofer only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Minirig 4 with subwoofer, which replaces the Minirig 3 with subwoofer.
If battery life is a priority, the Minirig 3 with subwoofer is rated for 30 hours versus 8 hours for the Vifa Oslo.
There is a real gap in water resistance: the Minirig 3 with subwoofer at Splash resistant (splashing) against the Vifa Oslo, which has no water resistance.
