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 #30 (rated 3.1/5) for the Soundboks Go. If you want one new, the Sony ULT Tower 7 ranks #1 at $648.
The Samsung MX-ST50B is the better-sounding, tougher choice. 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 IPX5, while the Soundboks Go has no water resistance. It supports aptX Bluetooth, which the Soundboks Go lacks. It has an adjustable EQ, which the Soundboks Go lacks. The tradeoff: Output drops sharply to 90W on battery, so it needs mains power for its full impact.
The Soundboks Go is the longer-running, lighter choice. Exceptional 40-hour battery life at mid-volume (10 hours at full volume), swappable design (second battery $200 available). It is rated for 40 hours of battery against 18 for the Samsung MX-ST50B. At 19.8 lbs (9 kg) it weighs noticeably less than the Samsung MX-ST50B at 26.2 lbs (11.9 kg). The tradeoff: Not as loud as the other Soundboks.
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 Sony ULT Tower 7 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.
