Short answer: the Tribit Stormbox Blast 2. It ranks #31 of 112 boombox speakers by sound quality, rated 3.8/5, at $279.99; the EcoXGear Defender ranks #84, rated 2.5/5, and costs $299.99, so there is little reason to consider the other one.
The Tribit Stormbox Blast 2 is the better-sounding choice. A big, waterproof party speaker with deep bass, very high volume, a 30 hour battery and two mic inputs. It supports AAC Bluetooth, which the EcoXGear Defender lacks. It plays in stereo from a single unit, unlike the EcoXGear Defender. The catch: Sounds quite muddy with the boosted lower and upper bass.
The EcoXGear Defender is the lighter pick. A rugged, floating waterproof speaker that gets very loud for its size, with a flashlight, bottle opener and power bank. At 10 lbs (4.54 kg) it weighs much less than the Tribit Stormbox Blast 2 at 19.2 lbs (8.7 kg). The tradeoff: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited.
Buy the Tribit Stormbox Blast 2. It is rated higher for sound quality than the EcoXGear Defender and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
