Short answer: the W-King X20S. It ranks #29 of 89 boombox speakers by sound quality, rated 3.8/5, at $150.99; the JBL Partybox On the Go ranks #59, rated 3.0/5, and costs $300, so there is not much of a tradeoff to weigh.
What the W-King X20S does well: Clearer and smoother than the larger W-King X20 at about half its size and weight, and in side by side tests it held its own against the Harman Kardon Go + Play 3, with nicer, more exposed mids and more volume. The tradeoff: Less bass and depth than the X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass.
What the JBL Partybox On the Go does well: JBL Partybox On the Go uses 5.1” woofer + tweeters. Watch for: Bass is limited by its 49Hz specification.
Buy the W-King X20S. 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.

W-King X20S: $150.99 AliExpress W-King eBay
Pros: Clearer and smoother than the larger W-King X20 at about half its size and weight, and in side by side tests it held its own against the Harman Kardon Go + Play 3, with nicer, more exposed mids and more volume. 140W RMS (180W peak), IPX7, Bluetooth 5.4, a built-in microphone, TF card, USB and aux playback, FM radio, a carry handle and a shoulder strap.
Cons: Less bass and depth than the X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass. With a flat EQ the bass is cut off, so it needs the bass boost. The JBL PartyBox Encore Essential 2 sounded better in a direct comparison. Sold direct from W-King in the US.

JBL Partybox On the Go: $300 Amazon eBay
Newer model: the JBL PartyBox On-The-Go 2 Plus, ranked higher, rated 4.4/5.
Pros: JBL Partybox On the Go uses 5.1” woofer + tweeters. Its 7.5 kg, claimed 6 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 94dB and limited-stereo playback make it a practical option for its intended room or portable use. A wireless microphone is included. Measured bass extension of 49Hz (-10dB).
Cons: Bass is limited by its 49Hz specification. No EQ adjustment. Battery life is short, and its sound trails the rest of the Partybox line.
