Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Onn XL Wireless Party Speaker ranks #11 of 40 party speakers by sound quality at $249; the Turtlebox Gen 3 ranks #71 of 76 boombox speakers by sound quality at $430.
The case for the Onn XL Wireless Party Speaker: A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. The catch: Sound favors punch and a forward/bright top end over refinement.
Why pick the Turtlebox Gen 3: Waterproof and crushproof, loud with punchy bass. The tradeoff: Sounds basically identical to the original and the Gen 2: each generation mainly added features, not sound quality.
Buy the Onn XL Wireless Party Speaker at $249 if you want a party speaker. Buy the Turtlebox Gen 3 at $430 if you want a boombox speaker instead.
There is a real battery-life gap here: the Turtlebox Gen 3 is rated for 25 hours, the Onn XL Wireless Party Speaker only 16 hours.
If water resistance matters to you, the Turtlebox Gen 3 at IP67 (brief submersion) holds up far better than the Onn XL Wireless Party Speaker at IPX4 (splashing).

The Two Speakers In Full
Onn XL Wireless Party Speaker: $249.00 Walmart eBay
Pros: A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. It plays loudly enough for backyard use and has punchy bass; owners especially like the wheels, telescoping handle and colorful light effects. At 44 lb it is still a substantial cabinet, but the trolley design makes moving it far easier than carrying it.
Cons: Sound favors punch and a forward/bright top end over refinement. Independent comparisons and owner reports find the bass less deep and the overall balance less satisfying than the JBL PartyBox 320; several consider the far-cheaper Onn Large Party gen 2 the better sound-per-dollar buy. Some owners report distortion or static at high volume, and a few report wireless-mic pairing/dropout problems. Large (30 inches tall, 44 lb) and only IPX4 splash-resistant, not a speaker to leave out in rain.

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.
