Short answer: the Zealot ZE41. It ranks #17 of 98 boombox speakers by sound quality, rated 4.1/5, at $259.90; the Sony ULT Field 7 ranks #59, rated 3.2/5, and costs $448.99, which makes this an easy call rather than a real tradeoff.
The Zealot ZE41 is the better-sounding choice. The absolute best value for the bass performance, play time and max volume in the boombox class. The catch: The heaviest and biggest boombox speaker around.
The Sony ULT Field 7 is the longer-running, lighter choice. It is rated for 30 hours of battery against 4 for the Zealot ZE41. At 13.9 lbs (6.3 kg) it weighs much less than the Zealot ZE41 at 25.3 lbs (11.48 kg). It is rated IP67 against IPX5 for the Zealot ZE41. The catch: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Buy the Zealot ZE41. It is rated higher for sound quality than the Sony ULT Field 7 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Pros: The absolute best value for the bass performance, play time and max volume in the boombox class.
Cons: The heaviest and biggest boombox speaker around. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.
