Short answer: the Minirig mk2 with subwoofer. It ranks #7 of 75 large speakers at $260; the Vifa Oslo ranks #8 and costs $550, so there is not much of a tradeoff to weigh.
The case for the Minirig mk2 with subwoofer: Very balanced sound. The tradeoff: Not stereo, app is buggy.
What the Vifa Oslo gets right: Extreme treble details with decent bass. Set against that: Dip at 270hz.
One note: the Minirig mk2 with subwoofer is discontinued, but it still ranks #7 of 75 large speakers, ahead of most of what is still sold new, so it is worth considering used.
Buy the Minirig mk2 with subwoofer if the ranking matters more than the price. Buy the Vifa Oslo if the price matters more than the ranking.

Vifa Oslo: $550 Amazon
Pros: Extreme treble details with decent bass. Full, natural, accurate sound at higher volumes. Rich, full bass from opposing 65mm woofers. Premium Kvadrat wool fabric with aluminum handle. 10 hour battery life.
Cons: Dip at 270hz. The Vifa Helsinki is cheaper and generally has a more neutral frequency response, I’d highly recommend getting one of those instead if you specifically want a Vifa. Not sure I can recommend this one generally these days, the Uboom L has 95% of the sound quality with more features and a way cheaper price.
