Short answer: the Soundcore Motion Boom+. It ranks #47 of 73 boombox speakers by sound quality at $140; the Turtlebox Gen 3 ranks #68 and costs $430, so there is not much of a tradeoff to weigh.
What the Turtlebox Gen 3 offers: Waterproof and crushproof, loud with punchy bass. 25+ hour battery life. USB-C charging and USB-C output charges other devices. True multi-speaker Party Mode added on top of stereo pairing, plus Bluetooth 5.4. Watch for: Sounds basically identical to the original and the Gen 2: each generation mainly added features, not sound quality. They pretty much lie about all their specs and sound horrible in all youtube sound samples. Will never hit its claimed 120db at a reasonable measuring distance. Putting your db meter right against the speaker doesn’t count, 1 meter distance is the standard. Barely any bass. Rattles at high volume. Looking at it, it appears to be a generic car 2-way 6x9 speaker in a plastic box.
What the Soundcore Motion Boom+ offers: 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. 13,400mAh battery for 20 hours (12-15 at high volume). IP67 waterproof, floats, rugged build inspires confidence. Bluetooth 5.3 multipoint pairing, Soundcore app EQ, PartyCast 2.0 mode. USB-C input, USB-A output for powerbank. Watch for: Default presets are all warm sounding with rolled off treble. Will need a custom EQ to get closer to neutral. A shrill sounding 6khz peak comes out when volume is above about 60%. Not much deeper bass than a Motion Boom and a lot less deep bass than other speakers in the class.
Buy the Soundcore Motion Boom+. It ranks higher for sound quality than the Turtlebox Gen 3 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Turtlebox Gen 3. It ranks near the bottom of the 73 boombox speakers, so look higher up the list instead.
