Short answer: the Teufel Boomster 4, if you are buying new. The Teufel Boomster 2021 ranks higher than the Turtlebox Grande (#46 vs #71 of 91 boombox speakers) but is discontinued; its replacement, the Teufel Boomster 4, is rated 3.4/5 and is still sold new.
The Turtlebox Grande is the longer-running choice. 10-inch woofer. It is rated for 25 hours of battery against 18 for the Teufel Boomster 2021. It links with other speakers (Turtlebox Party Mode), which the Teufel Boomster 2021 cannot. The catch: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
The Teufel Boomster 2021 is the better-sounding, lighter choice. At 8.3 lbs (3.75 kg) it weighs much less than the Turtlebox Grande at 18.8 lbs (8.53 kg).
Buy the Teufel Boomster 4, the replacement for the discontinued Teufel Boomster 2021; it is rated higher for sound quality than the Turtlebox Grande.

The Two Speakers In Full
Turtlebox Grande: $730.00 Amazon eBay
Same family: the Turtlebox Cub (smaller model, rated 3/5), the Turtlebox Ranger (smaller model, rated 3.5/5) and the Turtlebox Gen 3 (smaller model, ranked lower, rated 2.1/5). See every Turtlebox generation.
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). Measured bass extension of ~55Hz (-10dB).
Cons: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz. It is rated at just 86W, and like the smaller Turtleboxes it won’t reach its claimed 126dB at a standard one meter distance. Expensive for what it delivers. It charges only from its own barrel plug adapter, not USB-C.
