Short answer: the W-King T9 Pro, if you are buying new. The Samsung MX-ST50B ranks higher than it (#25 vs #36 of 51 party speakers, 3.6/5 vs 3.0/5) but is discontinued, so only consider it used; the W-King T9 Pro is still sold new at $171.49.
The Samsung MX-ST50B is the better-sounding, longer-running pick. A splash resistant party tower with two woofers, karaoke input, app EQ, and linking for up to ten speakers. It is rated for 18 hours of battery against 12 for the W-King T9 Pro. It is rated IPX5, while the W-King T9 Pro has no water resistance. It supports aptX Bluetooth, which the W-King T9 Pro lacks. Watch for: Output drops sharply to 90W on battery, so it needs mains power for its full impact.
The W-King T9 Pro is the lighter option. A rolling party speaker with dual woofers, a removable battery for long events, stereo pairing, and music synced lights. At 20 lbs (9.05 kg) it weighs noticeably less than the Samsung MX-ST50B at 26.2 lbs (11.9 kg). Watch for: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the W-King T9 Pro new; the Samsung MX-ST50B is no longer sold new, so it only makes sense as a used find.
