Short answer: the W-King T9 Pro. It ranks #36 of 51 party speakers by sound quality, rated 3.0/5, at $171.49. The Rockville Rock Party 6 ranks #51, rated 2.0/5, at $73.43, $98.06 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Rockville Rock Party 6 is the lighter pick. A budget battery party speaker with a woofer, tweeters, Bluetooth, and an aux input. At 11.9 lbs (5.4 kg) it weighs much less than the W-King T9 Pro at 20 lbs (9.05 kg).
The W-King T9 Pro is the better-sounding, longer-running pick. A rolling party speaker with dual woofers, a removable battery for long events, stereo pairing, and music synced lights. It is rated for 12 hours of battery against 6 for the Rockville Rock Party 6. The tradeoff: Reviewer comparisons describe the tuning as warm and gritty rather than clean or detailed.
Buy the W-King T9 Pro. It is rated higher for sound quality, and the $98.06 you would save on the Rockville Rock Party 6 does not close the gap.
