Short answer: both are discontinued, so this only matters if you are buying used. Used, the Sony SRS-XP500 is the better pick: it ranks #14 of 43 party speakers by sound quality (rated 4.0/5), against #24 (rated 3.6/5) for the Samsung MX-ST50B. If you want one new, the Sony ULT Tower 7 ranks #1 at $648.
What the Samsung MX-ST50B offers: Sounds reasonably balanced. Watch for: Not as deep bass as the Partybox 110 or other higher ranked speakers.
Buy the Sony SRS-XP500 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 Sony ULT Tower 7 instead.
If water resistance matters to you, the Samsung MX-ST50B at IPX5 (water jets) holds up far better than the Sony SRS-XP500 at no water resistance.

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.
