Short answer: the Vifa Helsinki for the higher ranking, the Zealot S97 for the lower price. The Vifa Helsinki ranks #1 of 75 large speakers at $400. The Zealot S97 ranks #45 at $65.86, $334.14 cheaper.
What the Vifa Helsinki gets right: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker. The tradeoff: No TWS pairing, looks like a purse, requires a hacked Vifa app (Android only post #48) to enable night mode to sound good.
On the Zealot S97 side: There is nothing else for $48 with that deep of bass and a reasonable tuning. The tradeoff: Doesn’t get very loud compared to other speakers in this class.
Buy the Vifa Helsinki if the ranking matters more than the price. Buy the Zealot S97 if the price matters more than the ranking.

The Two Speakers In Full
Vifa Helsinki: $400 Amazon
Pros: Generally regarded as the best midrange and treble sound quality of any battery powered Bluetooth speaker.
Cons: No TWS pairing, looks like a purse, requires a hacked Vifa app (Android only post #48) to enable night mode to sound good. Not sure I can recommend this one generally these days, the Uboom L has 98% of the sound quality with more features and a way cheaper price. There are mentions that the 2022 “new” version of this speaker doesn’t sound as good as Vifa was purchased by a Chinese company and laid off all the great sound engineers in the Austria office.
