Short answer: the JBL Partybox 300 for cleaner sound, the Soundcore Rave 3S for karaoke extras. The Rave 3S includes wireless microphones powered by 2 AA batteries plus a remote control, but it has some upper bass and upper-mids boost. The 300 has exceptional sound quality with crisp, crystal clear highs and midranges and hard punchy bass without muddiness, though it is hard to carry, too tall and drags on the ground.

Buy the JBL Partybox 330, the replacement for the discontinued JBL Partybox 300; it is rated higher for sound quality than the Soundcore Rave 3S.
There is a real battery-life gap here: the JBL Partybox 300 is rated for 18 hours, the Soundcore Rave 3S only 12 hours.
There is a real gap in water resistance: the Soundcore Rave 3S at IPX4 (splashing) against the JBL Partybox 300, which has no water resistance.
