Short answer: the Zealot S67, if you are buying new. The Vifa Helsinki ranks higher than it (#1 vs #113 of 115 large speakers, 4.8/5 vs 2.0/5) but is discontinued, so only consider it used; the Zealot S67 is still sold new at $70.94.
The Zealot S67 is the longer-running, tougher pick. A budget waterproof speaker with a long rated battery, USB-C charging, microSD playback, and stereo pairing. It is rated for 20 hours of battery against 8 for the Vifa Helsinki. It is rated IPX6, while the Vifa Helsinki has no water resistance. The tradeoff: Sound quality is the catch.
The Vifa Helsinki is the better-sounding, lighter option. A superb sounding battery powered speaker, with exceptionally clean mids and treble, now discontinued but worth buying used. At 3.1 lbs (1.4 kg) it weighs much less than the Zealot S67 at 5.3 lbs (2.4 kg). It supports aptX Bluetooth, which the Zealot S67 lacks. Watch for: 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 Zealot S67 if you want one new; the Vifa Helsinki is discontinued, so only look for it used.
