Short answer: the JBL Flip Essential 2. It ranks #71 of 150 medium speakers by sound quality, rated 3.3/5, at $85.90; the Teufel Rockster Go 2 ranks #80, rated 3.2/5, and costs $129.99, which makes this an easy call rather than a real tradeoff.
What the JBL Flip Essential 2 does well: Essentially a Flip 5 in a new shell: the same single 44 x 80mm racetrack driver and 20W amplifier, rated down to 65Hz. Watch for: There is no tweeter, and side by side comparisons found it does not sound as good as the Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight.
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.
Buy the JBL Flip Essential 2. It is rated higher for sound quality than the Teufel Rockster Go 2 and costs less, which makes it the one to get unless you need something the other one does better.
There is a real battery-life gap here: the Teufel Rockster Go 2 is rated for 15 hours, the JBL Flip Essential 2 only 10 hours.

The Two Speakers In Full
JBL Flip Essential 2: $85.90 Amazon eBay
Older model: the JBL Flip Essential (ranked lower, rated 3.2/5).
Pros: Essentially a Flip 5 in a new shell: the same single 44 x 80mm racetrack driver and 20W amplifier, rated down to 65Hz. In a side by side loudness test it got louder than the JBL Grip, and listeners comparing it with the Marshall Emberton found it more open sounding and clearer. IPX7 waterproof, 520 g, USB-C charging and Bluetooth 5.1 with two phones connected at once.
Cons: There is no tweeter, and side by side comparisons found it does not sound as good as the Flip 6, with less bass; its bass stops growing above about 70% volume, so turning it up mostly adds loudness, not weight. No app, no EQ, no PartyBoost or stereo pairing, a claimed 10 hours of battery, and IPX7 covers water but not dust.

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.
