Short answer: the Vifa Helsinki for the higher ranking, the JBL Xtreme 4 for the lower price. The Vifa Helsinki ranks #1 of 75 large speakers at $400. The JBL Xtreme 4 ranks #36 at $380, $20 cheaper.
The case for the JBL Xtreme 4: Removable battery. The catch: High priced.
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.
Buy the JBL Xtreme 4 if the price matters more than the ranking. Buy the Vifa Helsinki if the ranking matters more than the price.

JBL Xtreme 4: $380 Amazon Bhphotovideo
Pros: Removable battery. Slightly deeper bass than Xtreme 3. Use this EQ for the best sound quality.
Cons: High priced. Some bass boost. Dip in the upper bass to midrange makes it sound strange which cannot be EQd out. Some upper mids and treble boost at high levels.

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.
