Short answer: the JBL Partybox 330 for balance and battery, the Soundcore Rave 3S for karaoke. The Rave 3S includes wireless microphones powered by 2 AA batteries, a remote control and AI voice removal, but it boosts upper bass and upper mids and does not go as deep as a Partybox 110 or 120. The 330 adds a customizable lightshow and a removable battery, though its sound is nearly identical to the 310 and Stage 320 despite the power bump.
Buy the JBL Partybox 330. It is rated higher for sound quality, and saving $279.96 with the Soundcore Rave 3S does not make up for the sound-quality gap.
Battery life favors the JBL Partybox 330: rated for 18 hours against 12 hours for the Soundcore Rave 3S.
