Short answer: the Brane X for the deepest bass, the Soundcore Boom 2 for value. The Brane X is the absolute deepest bass in this category, but its upper bass is boosted around 120Hz and its treble rolled off. The Boom 2 still manages pretty deep bass for its size, though a single midrange driver means only the tweeters run in stereo.
Buy the Brane X when sound quality outweighs the price for you, and the Soundcore Boom 2 when the price outweighs sound quality instead.
Battery life favors the Soundcore Boom 2: rated for 24 hours against 12 hours for the Brane X.
