Short answer: the Tribit Stormbox Flow. It ranks #58 of 179 medium speakers by sound quality, rated 3.5/5, at $79.99; the Sonos Roam 2 ranks #94, rated 3.2/5, and costs $178, so there is not much of a tradeoff to weigh.
The Tribit Stormbox Flow is the deeper-bass, longer-running pick. A waterproof speaker with very long battery life, a carry handle, stereo pairing and a port that charges your phone. Its bass reaches about 47Hz before falling 10dB, against 63Hz for the Sonos Roam 2. It is rated for 30 hours of battery against 10 for the Sonos Roam 2. It is rated IPX7 against IPX5 for the Sonos Roam 2. Watch for: Midrange and bass are weirdly recessed about 4db below 700Hz.
The Sonos Roam 2 is the lighter option. A small Wi-Fi and Bluetooth speaker with water resistance, Alexa built in and Sonos multiroom support. At 0.9 lbs (429 g) it weighs noticeably less than the Tribit Stormbox Flow at 1.4 lbs (657 g). Watch for: Exact same sound quality as the original Sonos Roam.
Buy the Tribit Stormbox Flow. It is rated higher for sound quality than the Sonos Roam 2 and costs less, which makes it the one to get unless you need something the other one does better.
