Short answer: the Vifa Helsinki for the higher ranking, the W-King T9 for the lower price. The Vifa Helsinki ranks #1 of 75 large speakers at $400. The W-King T9 ranks #37 at $78.83, $321.17 cheaper.
On the Vifa Helsinki side: 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.
The case for the W-King T9: 80W output power, 106dB max volume, 24-hour battery life, power bank function, Bluetooth 5.3 with 100ft range. The catch: Peaks in the upper mids which makes it sound a bit harsh.
Buy the Vifa Helsinki if the ranking matters more than the price. Buy the W-King T9 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.
