Short answer: the JBL Partybox On the Go. It ranks #44 of 73 boombox speakers by sound quality at $300; the Turtlebox Grande ranks #54 and costs $730, so there is not much of a tradeoff to weigh.
What the Turtlebox Grande offers: 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). Watch for: 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.
What the JBL Partybox On the Go offers: Included wireless microphone. Watch for: Poor water rating. Horrible battery life. Probably the worst sounding of the Partybox line.
Buy the JBL Partybox On the Go. It ranks higher for sound quality than the Turtlebox Grande and costs less, so there is no real case for the other one.
If battery life is a priority, the Turtlebox Grande is rated for 25 hours versus 6 hours for the JBL Partybox On the Go.
If water resistance matters to you, the Turtlebox Grande at IP67 (brief submersion) holds up far better than the JBL Partybox On the Go at IPX4 (splashing).
