Short answer: the Onn Medium Party Speaker Gen 2. It ranks #65 of 112 boombox speakers by sound quality, rated 3.1/5, at $90; the JBL Partybox On the Go ranks #66, rated 3.0/5, and costs $249.95, so there is not much of a tradeoff to weigh.
The Onn Medium Party Speaker Gen 2 is the better deal. An 8-inch woofer, LED lights, a karaoke mic input with echo, FM radio and a claimed 20 hours of battery come in an IPX7 cabinet for far less money. Its sound lacks the detail and deep bass of the Onn Large Party Gen 2, and it is sold only in the US and Canada.
The PartyBox On the Go is built around its wireless microphone. A 5.1-inch woofer and tweeters run at 100W, with a wireless mic in the box and USB-C charging. JBL rates its battery for just 6 hours and its output at 94dB, it has no EQ, and its sound trails the rest of the PartyBox line. It also weighs more, at 16.5 lbs (7.5 kg) against 11 lbs (5 kg).
Buy the Onn Medium Party Speaker Gen 2. It is rated higher for sound quality than the JBL Partybox On the Go and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
There is a real gap in water resistance: the Onn Medium Party Speaker Gen 2 at IPX7 (brief submersion) against the JBL Partybox On the Go, which has IPX4 (splashing).
