Short answer: the JBL Partybox Encore Essential 2 for off axis sound, the ZZA K8 for value. The Essential 2’s dome tweeters over cone appear better off axis, though it is missing a little bit of upper bass. The K8 is completely insane value for the money, but its very V curve frequency response can be harsh in the treble range.
On the JBL Partybox Encore Essential 2 side: Appears to have better off axis performance due to the move to dome tweeters over cone. Set against that: Missing a little bit of upper bass.
The case for the ZZA K8: Completely insane value for the money. The tradeoff: Very V curve frequency response, can be harsh in the treble range.
Buy the JBL Partybox Encore Essential 2 if sound quality matters more than the price. Buy the ZZA K8 if the price matters more than sound quality.
There is a real battery-life gap here: the ZZA K8 is rated for 30 hours, the JBL Partybox Encore Essential 2 only 15 hours.

The Two Speakers In Full
JBL Partybox Encore Essential 2: $254.12 Amazon B&H Photo Video eBay
Pros: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. Independent testing finds a balanced midrange, genuinely punchy low bass and enough output for a backyard gathering; its dome tweeters also improve the earlier Encore’s high-frequency behavior.
Cons: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume. Bluetooth latency can cause lip-sync issues, its IPX4 rating only covers splashes, and it omits the wireless microphones bundled with the non-Essential Encore 2.

ZZA K8: $40 after clipped coupon, Discontinued eBay
Pros: Completely insane value for the money. Comes with 2 metal body wireless microphones that are USB-C chargeable. Comes with Chinese labeled infrared remote control. Has voice delete function that works quite well. Adjustable microphone reverb. Pretty good build quality. The default EQ is the most balanced, the other two sound muffled.
Cons: Very V curve frequency response, can be harsh in the treble range. Treble is boosted a good +10dB. Midbass is recessed. Slight distortion issue at all volume levels due to the bass high pass filter being set too low. Discontinued and no longer sold new. Discontinued.
