Onn Large Party gen 2 rates higher and costs less; W-King T9 Pro adds a removable battery and dual 6.5-inch woofers for more raw output. They rank 19 of 51 and 36 of 51.
W-King T9 Pro pairs dual 6.5” woofers with a swappable battery, TWS pairing and music-synced lighting, useful for long events, but reviewer comparisons describe its tuning as warm and gritty, and it has no water rating.
Onn Large Party gen 2 adds wheels, a handle and karaoke mic/guitar inputs at a lower price, with real bass impact in independent testing, though Consumer Reports found boomy bass and smeared treble.
Buy the Onn Large Party gen 2 for the better rating and lower price. Buy the W-King T9 Pro if a swappable battery and higher raw output matter more for long events.
There is a real gap in water resistance: the Onn Large Party gen 2 at IPX4 (splashing) against the W-King T9 Pro, which has no water resistance.

The Two Speakers In Full
Onn Large Party gen 2: $129 Walmart eBay
Pros: A remarkably full-featured, manageable 9.5kg party speaker: wheels and handle, FM radio, aux, USB-A charging, mic and guitar inputs with karaoke echo, and Party Sync. Independent testing confirms bass with real impact and enough output for a large room; it is a clear improvement over the Gen 1 for low-end weight.
Cons: The low price shows in the refinement. Consumer Reports found boomy bass, hazy/grainy mids, a prominent smeared treble and a narrow, two-dimensional soundfield; it also notes distortion or other audio issues. There is no app or EQ to tame the tuning, and IPX4 only covers splashes rather than rain or immersion.

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.
