Short answer: the Teufel Rockster Go 2 if sound quality matters most, the Soundcore 2 if price matters most. The Teufel Rockster Go 2 ranks #80 of 150 medium speakers, rated 3.2/5, at $129.99. The Soundcore 2 ranks #92, rated 3.0/5, at $29.99, $100 cheaper.
The case for the Teufel Rockster Go 2: 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. The tradeoff: There is no companion app or 3.5 mm input.
What the Soundcore 2 does well: Soundcore 2 uses 2x 38mm fullrange. The tradeoff: Its 70Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
Buy the Teufel Rockster Go 2 if sound quality is the priority over the price, or the Soundcore 2 if the price is the priority over sound quality.
There is a real battery-life gap here: the Soundcore 2 is rated for 24 hours, the Teufel Rockster Go 2 only 15 hours.

The Two Speakers In Full
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.
