Short answer: the JBL Partybox Encore 2, for cleaner off axis sound. Its dome tweeters over cone appear to give better off axis performance, though it is missing a little bit of upper bass. The Tribit Stormbox Blast 2 goes pretty deep, but it sounds quite muddy with the boosted lower and upper bass.
Buy the JBL Partybox Encore 2. It is rated higher for sound quality, and saving $50.01 with the Tribit Stormbox Blast 2 does not make up for the sound-quality gap.
Battery life favors the Tribit Stormbox Blast 2: rated for 30 hours against 15 hours for the JBL Partybox Encore 2.
If water resistance matters to you, the Tribit Stormbox Blast 2 at IP67 (brief submersion) holds up far better than the JBL Partybox Encore 2 at IPX4 (splashing).
