Short answer: the Ultimate Ears Megaboom 3. It ranks #83 of 136 medium speakers by sound quality; the Teufel Rockster Go ranks #103.
What the Teufel Rockster Go gets right: Clear mid-range with bright treble, wide soundstage via Dynamore processing, IP67 waterproof and durable, solid battery life, compact design with carrying strap. The tradeoff: Rolled off treble, muffled sound, mids sound strange.
What the Ultimate Ears Megaboom 3 offers: IP67 rated, floats, and survives drops from up to 1 meter. Set against that: Not stereo, barely any bass.
One note: the Teufel Rockster Go is discontinued, but it still ranks #103 of 136 medium speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Teufel Rockster Go if the price matters more than sound quality. Buy the Ultimate Ears Megaboom 3 if sound quality matters more than the price.
If sound quality matters at all to you, skip the Teufel Rockster Go. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
If battery life is a priority, the Ultimate Ears Megaboom 3 is rated for 20 hours versus 12 hours for the Teufel Rockster Go.

Ultimate Ears Megaboom 3: $163 Amazon
Pros: IP67 rated, floats, and survives drops from up to 1 meter. 20 hour battery life - about double most speakers this size.
Cons: Not stereo, barely any bass. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2018. Not technically a 360 speaker, only front and rear.
