Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Charge 3 is the better pick: it ranks #91 of 175 medium speakers by sound quality (rated 3.2/5), against #172 (rated 2.0/5) for the Zealot S61. If you want one new, the JBL Charge 6 replaces the JBL Charge 3 and is rated 4.2/5 at $119.95.
The JBL Charge 3 is the better-sounding option. Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. It plays in stereo from a single unit, unlike the Zealot S61. The tradeoff: Less clarity than the JBL Flip 4.
The Zealot S61 is the longer-running choice. 20W output, IPX7 waterproof, exceptional 40-hour battery life, Bluetooth 5.2, TWS stereo pairing, compact 1.5 lbs (665 g) design, single full-range driver, built-in microphone, AUX input, USB-C charging. It is rated for 40 hours of battery against 20 for the JBL Charge 3. It charges over USB-C rather than Micro USB. Watch for: Sounds like a soup can, no bass at all.
Buy the JBL Charge 3 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Charge 6, which replaces the JBL Charge 3.
