Short answer: the Marshall Stockwell 2. It ranks #11 of 77 large speakers by sound quality at $200; the Ultimate Ears Megablast ranks #61 and costs $240, so there is little reason to consider the other one.
What the Marshall Stockwell 2 offers: Possibly the most natural sounding Marshall speaker. Excellent off-axis. Watch for: Not stereo. Not very loud. Uses added DSP reverb which audio purists may find annoying.
What the Ultimate Ears Megablast offers: Alexa integration (Wi-Fi + Bluetooth). 93dB loudest in UE lineup, 40% louder than Megaboom. IP67 waterproof and drop-proof. 16 hour battery. Party mode connects up to 8 speakers. Can use while charging to keep Alexa on 24/7. Watch for: Bass is not very deep compared to the competition
Buy the Marshall Stockwell 2. It ranks higher for sound quality than the Ultimate Ears Megablast and costs less, which settles it without a real tradeoff to make.
Skip the Ultimate Ears Megablast if sound quality matters to you. It ranks near the bottom of the 77 large speakers.
