Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Bose SoundLink Color II is the better pick: it ranks #121 of 164 medium speakers by sound quality (rated 2.7/5), against #126 (rated 2.6/5) for the Teufel Rockster Go. Both are rated below 3.0/5 among the 164 medium speakers, and the Earfun Uboom L, ranked #1 at $49.79, is a better place to start if sound quality matters.
Buy the Bose SoundLink Color II only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Earfun Uboom L instead.
