Short answer: the B&O Beolit 20, if you are buying new. The Teufel Boomster 2021 measures as well as it (#45 vs #42 of 89 boombox speakers, 3.4/5 vs 3.4/5) but is discontinued, so only consider it used; the B&O Beolit 20 is still sold new at $749.
The case for the B&O Beolit 20: B&O Beolit 20 uses 2x 30mm tweeters + 2x 40mm mid-range + 1x 60mm woofer + dual passive radiators. The catch: Bass is limited by its 45Hz specification.
The case for the Teufel Boomster 2021: Teufel Boomster 2021 uses 1x 110mm (4.3”) woofer + 2x 65mm midrange drivers + 2x 20mm tweeters. The catch: There is no companion app.
Buy the B&O Beolit 20 if you want one new; the Teufel Boomster 2021 is discontinued, so only look for it used.
There is a real battery-life gap here: the Teufel Boomster 2021 is rated for 18 hours, the B&O Beolit 20 only 8 hours.
Water resistance is not close: the Teufel Boomster 2021 is rated at IPX7 (brief submersion), well ahead of the B&O Beolit 20 at IPX4 (splashing).
