Short answer: neither is a stand out, so pick the Teufel Rockster Go for durability. The Go is IP67 waterproof with a wide Dynamore soundstage and solid battery life, but our notes describe rolled off treble and not very deep bass. The Soundcore Flare 2 is not technically a 360 speaker, only front and rear, and it suffers from rolled off treble and thuddy bass, though a community EQ preset is suggested for it. Both are rated below 3.0/5 among the 157 medium speakers; for better sound, the Earfun Uboom L ranks #1 at $49.79.
Buy the Teufel Rockster Go or the Soundcore Flare 2, whichever you find used in better condition; both are discontinued. For a new speaker, start with the Earfun Uboom L instead.
