Short answer: the Monster Rockin’ Roller 270, though neither ranks well in its class. Both are rated 2.1/5 for sound quality (#70 and #71 of 76 boombox speakers), and the Monster Rockin’ Roller 270 costs $249 against $430 for the Turtlebox Gen 3, so with nothing between them on sound quality, price settles it. Both are rated below 3.0/5 among the 76 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
Why pick the Monster Rockin’ Roller 270: 100 hour battery life. Watch for: Bass not as deep as competitors, less neutral than ION speakers.
Why pick the Turtlebox Gen 3: Waterproof and crushproof, loud with punchy bass. Watch for: Sounds basically identical to the original and the Gen 2: each generation mainly added features, not sound quality.
Buy the Monster Rockin’ Roller 270. Both are rated the same for sound quality, and it costs $181 less than the Turtlebox Gen 3.
If battery life is a priority, the Monster Rockin’ Roller 270 is rated for 100 hours versus 25 hours for the Turtlebox Gen 3.
If water resistance matters to you, the Turtlebox Gen 3 at IP67 (brief submersion) holds up far better than the Monster Rockin’ Roller 270 at IPX4 (splashing).

Turtlebox Gen 3: $430.00 Amazon eBay
Older models: the Turtlebox Gen 2 (rated 2.1/5) and the Turtlebox (rated 2.1/5).
Pros: 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. Measured bass extension of ~65Hz (-10dB).
Cons: 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.
