These sit in different size classes, so this is not a straight ranking comparison. The Tribit Stormbox Lava ranks #3 of 120 large speakers by sound quality at $139.99; the Sony ULT Field 3 ranks #71 of 179 medium speakers by sound quality at $208.
The case for the Tribit Stormbox Lava: A loud, waterproof large speaker with strong bass, a long battery and an aux input, for far less than its rivals. It keeps a wired aux input, which the Sony ULT Field 3 lacks. Watch for: XBass can make the low end muddy and obscure vocals, while the deepest notes lose authority and clarity falls at maximum volume.
The Sony ULT Field 3 is the lighter option. A rugged waterproof stereo speaker with long battery life, a detailed app EQ, a shoulder strap and a phone charging port. At 2.6 lbs (1.2 kg) it weighs much less than the Tribit Stormbox Lava at 5.2 lbs (2.37 kg). It supports LDAC Bluetooth, which the Tribit Stormbox Lava lacks. It links with other speakers (Party Connect up to 100 speakers), which the Tribit Stormbox Lava cannot. Watch for: Sounds a bit hollow, a bit boosted in the treble.
Buy the Tribit Stormbox Lava ($139.99) for a large speaker; the Sony ULT Field 3 ($208) suits a medium speaker instead.
