These sit in different size classes, so this is not a straight ranking comparison. The JBL PartyBox On-The-Go 2 Plus ranks #5 of 113 boombox speakers by sound quality at $349.95; the Soundcore Rave 3S ranks #20 of 53 party speakers by sound quality at $299.99.

Different sizes. The On-The-Go 2 Plus is a 14.2 lbs (6.45 kg) boombox. The Rave 3S is a 21.6 lbs (9.8 kg) party speaker. Each is rated within its own class.
Sound: in a side by side test the Rave 3S leaned brighter with more kick in its bass, while the On-The-Go 2 Plus had smoother, cleaner bass. The Rave 3S has some upper bass and upper mid boost.
Both remove vocals with AI. The Rave 3S includes two AA-powered wireless mics and a remote. The On-The-Go 2 Plus includes one rechargeable mic, which picked up less handling noise in testing.
Batteries: the On-The-Go 2 Plus uses a removable battery with a claimed 15 hours. The Rave 3S claims 12 hours and charges over USB-C, but its battery is not easy to swap. Both are IPX4.
Buy the JBL PartyBox On-The-Go 2 Plus ($349.95) for a boombox speaker; the Soundcore Rave 3S ($299.99) suits a party speaker instead.
