Short answer: the Marshall Middleton II. It ranks #31 of 105 large speakers by sound quality, rated 4.1/5, at $329.99. The Zealot S67 ranks #104, rated 2.0/5, at $70.94, $259.05 cheaper, which does not close the gap in sound quality.
The Marshall Middleton II is the better-sounding, longer-running choice. Very deep bass for the size/weight. It is rated for 30 hours of battery against 20 for the Zealot S67. At 4 lbs (1.8 kg) it weighs noticeably less than the Zealot S67 at 5.3 lbs (2.4 kg). It links with other speakers (Marshall Stack), which the Zealot S67 cannot. The tradeoff: Bass boosted which drowns out the midrange.
Why pick the Zealot S67: It offers a lot of practical hardware for a 5.3 lbs (2.4 kg) budget speaker: IPX6 water resistance, USB-C charging, aux and microSD playback, speakerphone, a claimed 20-hour battery and TWS pairing for a second unit. The catch: Sound quality is the catch.
Buy the Marshall Middleton II. It is rated higher for sound quality, and the $259.05 you would save on the Zealot S67 does not close the gap.

Zealot S67: $70.94 AliExpress $70.94 eBay
Pros: It offers a lot of practical hardware for a 2.4kg budget speaker: IPX6 water resistance, USB-C charging, aux and microSD playback, speakerphone, a claimed 20-hour battery and TWS pairing for a second unit. The large enclosure and dual-driver/passive-radiator layout can provide useful party-level volume.
Cons: Sound quality is the catch. Independent reviewer comparisons report obvious distortion once volume rises past roughly halfway, little true deep bass, and a rolled-off, low-detail treble. There is no app or real EQ to correct that balance, so its long feature list does not make it a good pick for attentive music listening.
