Short answer: both are discontinued, so this only matters if you are buying used. Used, the Samsung MX-ST50B is the better pick: it ranks #25 of 44 party speakers by sound quality (rated 3.6/5), against #33 (rated 2.7/5) for the Onn Large Party gen 1. If you want one new, the JBL Partybox Club 120 ranks #6 at $349.95.
The Samsung MX-ST50B is the better-sounding, longer-running option. A 240W sound tower with two 6.5-inch woofers and two tweeters, IPX5 protection, app EQ, aux and USB playback, karaoke input and Samsung Group Play for linking up to 10 speakers. It is rated for 18 hours of battery against 13 for the Onn Large Party gen 1. It is rated IPX5, while the Onn Large Party gen 1 has no water resistance. It supports aptX Bluetooth, which the Onn Large Party gen 1 lacks. Watch for: Output drops sharply to 90W on battery, so it needs mains power for its full impact.
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. The tradeoff: Sound is not a strong reason to seek one out.
Buy the Samsung MX-ST50B only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the JBL Partybox Club 120 instead.

The Two Speakers In Full
Samsung MX-ST50B: $300 Discontinued Amazon eBay
Pros: A 240W sound tower with two 6.5-inch woofers and two tweeters, IPX5 protection, app EQ, aux and USB playback, karaoke input and Samsung Group Play for linking up to 10 speakers. Hands-on reviews find it capable of clear, punchy sound and impressive output for indoor parties, while its 18-hour claimed battery supports more casual use away from mains power.
Cons: Output drops sharply to 90W on battery, so it needs mains power for its full impact. Bass is not as deep as stronger dedicated party speakers, and at 11.9kg its tall enclosure is less convenient to carry. It lacks TWS stereo pairing, so the Group Play feature favors shared party coverage rather than a conventional stereo image. Discontinued.

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.
