Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Soundcore Rave 3S ranks #20 of 53 party speakers by sound quality at $299.99; the Turtlebox Grande ranks #81 of 113 boombox speakers by sound quality at $730.
Why pick the Soundcore Rave 3S: A big party speaker with two wireless microphones, a remote, and a vocal removal feature for karaoke nights. It has an adjustable EQ, which the Turtlebox Grande lacks. The tradeoff: Some upper bass and upper mids boost.
The Turtlebox Grande is the longer-running, tougher pick. A rugged, submersible, crush-proof speaker with a 10 inch woofer and a battery that lasts for days. It is rated for 25 hours of battery against 12 for the Soundcore Rave 3S. It is rated IP67 against IPX4 for the Soundcore Rave 3S. It plays in stereo from a single unit, unlike the Soundcore Rave 3S. Watch for: In YouTube sound samples it sounds only okay, and bass is shallow for a 10 inch woofer, only down 10dB at about 55Hz.
Buy the Soundcore Rave 3S ($299.99) for a party speaker; the Turtlebox Grande ($730) suits a boombox speaker instead.
