Short answer: the W-King T9 Pro. It ranks #30 of 43 party speakers by sound quality, rated 3.0/5, at $171.49. The Onn Large Party gen 1 ranks #32, rated 2.7/5, at $100, $71.49 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the W-King T9 Pro: A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. The catch: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
The case for the Onn Large Party gen 1: A genuinely useful feature set for a compact party speaker: FM radio, 3.5mm aux, USB-A phone charging, a mic/guitar input, lights, and Party Sync pairing. Watch for: Sound is not a strong reason to seek one out.
One note: the Onn Large Party gen 1 is discontinued and no longer widely available new.
Buy the W-King T9 Pro. It is rated higher for sound quality, and saving $71.49 with the Onn Large Party gen 1 does not make up for the sound-quality gap.

W-King T9 Pro: $171.49 AliExpress eBay
Pros: A feature-rich rolling party speaker with dual 6.5-inch woofers, removable battery, TWS pairing, bass presets and music-synced lighting. The swappable battery is especially useful for long events, and its strong output gives it much more headroom than compact Bluetooth speakers.
Cons: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed. Its claimed output figures should not be mistaken for neutral sound quality, and a large cabinet with no stated water rating is a poor fit for wet outdoor use.

Onn Large Party gen 1: $100 Discontinued eBay
Newer model: the Onn Large Party gen 2, ranked higher, rated 3.9/5.
Pros: A genuinely useful feature set for a compact party speaker: FM radio, 3.5mm aux, USB-A phone charging, a mic/guitar input, lights, and Party Sync pairing. Its rolling 10.5kg cabinet, carry handle and claimed 13-hour battery make it easy to take to casual outdoor gatherings, and it can play louder than a typical small Bluetooth speaker. Measured bass extension of ~60Hz (-10dB).
Cons: Sound is not a strong reason to seek one out. Reviewer comparisons find limited deep bass (about 60Hz at -10dB), uneven mids and a boxy, strained presentation at high volume. It has no app or EQ, no water rating, and is discontinued; the newer Onn Large Party gen 2 is the more sensible choice when available.
