Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL PartyBox On-The-Go 2 Plus ranks #5 of 113 boombox speakers by sound quality at $349.95; the Soundboks Rider ranks #31 of 53 party speakers by sound quality at $599.

Why pick the JBL PartyBox On-The-Go 2 Plus: A well balanced karaoke party speaker with clean bass, clear vocals, on-board vocal removal, an included wireless mic and a removable battery. It links with other speakers (Auracast), which the Soundboks Rider cannot. The tradeoff: The bass has less kick and physical impact than the JBL Partybox Encore 2 or JBL Partybox Club 120, and the JBL Partybox Club 120 gets noticeably louder.
The Soundboks Rider is the longer-running, tougher option. A light, rugged party speaker with a swappable battery that lasts all day at mid volume and an app with a six band EQ. It is rated for 35 hours of battery against 15 for the JBL PartyBox On-The-Go 2 Plus. It is rated IP66 against IPX4 for the JBL PartyBox On-The-Go 2 Plus. The tradeoff: Its sealed 8in woofer runs out of real bass at high volume: Xander measured the -6 dB point rising to roughly 75 to 85 Hz at maximum, with 40 Hz some 20 dB down, and M1M heard the bass pulled back toward the upper bass above mid volume.
Buy the JBL PartyBox On-The-Go 2 Plus ($349.95) for a boombox speaker; the Soundboks Rider ($599) suits a party speaker instead.
