Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Turtlebox Grande ranks #56 of 75 boombox speakers by sound quality at $700; the Onn Large Party gen 2 ranks #19 of 51 party speakers by sound quality at $129.
What the Turtlebox Grande gets right: 10-inch woofer. IP67 submersible shell with crush-proof ABS exterior. 158Wh battery provides ~3 days of playback. Bluetooth 5.4, party mode (100+ speakers). Set against that: They pretty much lie about all their specs and sound just okay in all youtube sound samples. Only 100w will never hit 126db at a reasonable measuring distance. Putting your db meter right against the speaker doesn’t count, 1 meter distance is the standard.
What the Onn Large Party gen 2 offers: An insane value speaker. Easy to move around because it has a handle and wheels. A huge improvement over the gen 1 with much deeper bass. The tradeoff: Not quite as loud as the old one. Not as deep bass as the top ranked.
Buy the Turtlebox Grande ($700) for a boombox speaker; the Onn Large Party gen 2 ($129) suits a party speaker instead.
There is a real battery-life gap here: the Turtlebox Grande is rated for 25 hours, the Onn Large Party gen 2 only 12 hours.
There is a real gap in water resistance: the Turtlebox Grande at IP67 (brief submersion) against the Onn Large Party gen 2, which has IPX4 (splashing).

The Two Speakers In Full
Turtlebox Grande: $700.00 Amazon eBay
Pros: 10-inch woofer. IP67 submersible shell with crush-proof ABS exterior. 158Wh battery provides ~3 days of playback. Bluetooth 5.4, party mode (100+ speakers).
Cons: They pretty much lie about all their specs and sound just okay in all youtube sound samples. Only 100w will never hit 126db 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 for a 10” woofer. Overpriced and not worth it.
