Short answer: the B&O Beosound A1 2nd gen. It ranks #11 of 164 medium speakers by sound quality, rated 4.3/5, at $395. The Teufel Rockster Go 2 ranks #91, rated 3.2/5, at $129.99, $265.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The B&O Beosound A1 2nd gen is the better-sounding, lighter choice. At 1.2 lbs (558 g) it weighs noticeably less than the Teufel Rockster Go 2 at 1.6 lbs (735 g). It supports aptX Adaptive Bluetooth, which the Teufel Rockster Go 2 lacks.
The case for the Teufel Rockster Go 2: At 1.6 lbs (0.74 kg), the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. It plays in stereo from a single unit, unlike the B&O Beosound A1 2nd gen. The catch: There is no companion app or 3.5 mm input.
Buy the B&O Beosound A1 2nd gen. It is rated higher for sound quality, and the $265.01 you would save on the Teufel Rockster Go 2 does not close the gap.

Teufel Rockster Go 2: $129.99 Amazon eBay
Older model: the Teufel Rockster Go (ranked lower, rated 2.6/5).
Pros: At 0.74 kg, the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. Independent listening found a balanced, clear midrange and tuneful bass at sensible levels.
Cons: There is no companion app or 3.5 mm input. Reviewers found it loses some definition at maximum volume, and the claimed battery figure is optimistic for loud outdoor playback.
