Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Ultimate Ears Wonderboom is the better pick: it ranks #109 of 164 medium speakers by sound quality (rated 2.9/5), against #128 (rated 2.6/5) for the Soundcore Flare 2. Both are rated below 3.0/5 among the 164 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #2 at $49.79.
Buy the Ultimate Ears Wonderboom 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.
