Short answer: the LG Xboom XG7 on price and battery, the Megablast on voice control, though neither ranks well in its class. The XG7 is the longer-running speaker with an impressive 24-hour battery and costs $120 against $240, but it has a peaky midrange and rolled off treble. The Megablast adds Alexa integration over Wi-Fi and Bluetooth, though its bass is not very deep compared to the competition. Both are rated below 3.0/5 among the 97 large speakers; for better sound, the Tribit Stormbox Lava ranks #3 at $100.
Buy the Ultimate Ears Megablast only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Tribit Stormbox Lava instead.
