Short answer: the W-King D20. It ranks #37 of 91 boombox speakers by sound quality, rated 3.6/5, at $193; the Turtlebox Gen 3 ranks #85, rated 2.1/5, and costs $430, so there is not much of a tradeoff to weigh.
The Turtlebox Gen 3 is the lighter option. Waterproof (IP67, and it floats) and crushproof, with stainless steel hardware and quality amplifier parts inside. At 10 lbs (4.54 kg) it weighs noticeably less than the W-King D20 at 14.3 lbs (6.5 kg). It links with other speakers (Turtlebox Party Mode), which the W-King D20 cannot. The tradeoff: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality.
The W-King D20 is the better-sounding, deeper-bass option. Comes with 2 wireless microphones. Its bass reaches about 42Hz before falling 10dB, against 65Hz for the Turtlebox Gen 3. It has an adjustable EQ, which the Turtlebox Gen 3 lacks. The catch: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the W-King D20. It is rated higher for sound quality than the Turtlebox Gen 3 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
Turtlebox Gen 3: $430.00 Amazon eBay
Older models: the Turtlebox Gen 2 (ranked lower, rated 2.1/5) and the Turtlebox (ranked lower, rated 2.1/5). See every Turtlebox generation.
Same family: the Turtlebox Cub (smaller model, rated 3/5), the Turtlebox Ranger (smaller model, rated 3.5/5) and the Turtlebox Grande (larger model, ranked higher, rated 2.6/5).
Pros: Waterproof (IP67, and it floats) and crushproof, with stainless steel hardware and quality amplifier parts inside. Loud for its class: Williston Audio Labs measured 102 dB at max volume, well above a Kicker Bullfrog BF400’s 96 dB. A big 85Wh battery rated for 25+ hours, a USB-C output that charges other devices, aux and microphone inputs, and true multi-speaker Party Mode on top of stereo pairing, plus Bluetooth 5.4. Measured bass extension of ~65Hz (-10dB).
Cons: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality. The amp is tuned to a V shape, with boosted lows and highs and a dip in the mids, but the boost can’t make up for shallow extension: the bass is only down 10dB at about 65Hz, so there’s little real low end despite the boomy upper bass. The amp delivers only about 12W RMS at 1% distortion. In Williston Audio Labs’ side by side test most listeners preferred the much smaller Kicker Bullfrog BF400 for its cleaner sound, and a Pioneer PBM5 played louder at 105 dB. Nowhere near its claimed 120dB at a reasonable measuring distance. Rattles at high volume. It charges only from its own 15V barrel plug brick, not USB-C, and has no app or EQ. Inside is essentially a car audio 6x9 two way speaker in a plastic box.
