Short answer: the JBL Charge 3 for better sound quality, the Zealot S61 for the lower price. The JBL Charge 3 ranks #67 of 136 medium speakers at $80. The Zealot S61 ranks #134 at $20, $60 cheaper.
What the JBL Charge 3 offers: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. IPX7 rated; built-in noise/echo-cancelling speakerphone. Watch for: Less clarity than the Flip 4. Battery failures are common.
What the Zealot S61 offers: 20W output, IPX7 waterproof, exceptional 40-hour battery life, Bluetooth 5.2, TWS stereo pairing, compact 665g design, single full-range driver, built-in microphone, AUX input, USB-C charging Watch for: Sounds like a soup can, no bass at all. Weird frequency response all over.
Buy the JBL Charge 3 if sound quality is the priority over the price, or the Zealot S61 if the price is the priority over sound quality.
The Zealot S61 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
If battery life is a priority, the Zealot S61 is rated for 40 hours versus 20 hours for the JBL Charge 3.
