Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Onn Large Party gen 2 ranks #17 of 53 party speakers by sound quality at $129; the W-King X20 ranks #43 of 113 boombox speakers by sound quality at $229.99.

What the Onn Large Party gen 2 does well: A budget party speaker on wheels with real bass impact, karaoke inputs and an FM radio. It links with other speakers (Party Sync Mode), which the W-King X20 cannot. The tradeoff: The low price shows in the refinement.
The W-King X20 is the longer-running, lighter pick. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It is rated for 24 hours of battery against 12 for the Onn Large Party gen 2. At 15.9 lbs (7.2 kg) it weighs noticeably less than the Onn Large Party gen 2 at 20.9 lbs (9.5 kg). It is rated IPX6 against IPX4 for the Onn Large Party gen 2. The catch: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the Onn Large Party gen 2 at $129 if you want a party speaker. Buy the W-King X20 at $229.99 if you want a boombox speaker instead.
