Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Partybox 100 is the better pick: it ranks #8 of 46 party speakers by sound quality (rated 4.4/5), against #44 (rated 2.1/5) for the Sony GTK-XB60. If you want one new, the JBL Partybox Club 120 replaces the JBL Partybox 100 and is rated 4.5/5 at $349.95.
The JBL Partybox 100 is the better-sounding, deeper-bass option. Quite neutral sound, pretty deep bass. Its bass reaches about 41Hz before falling 10dB, against 60Hz for the Sony GTK-XB60. The catch: A slight peak in the upper mids.
Why pick the Sony GTK-XB60: 60W powerful sound performance with extra-bass technology for deep, punchy output. It supports LDAC Bluetooth, which the JBL Partybox 100 lacks. It links with other speakers (Partychain up to 100 speakers), which the JBL Partybox 100 cannot. Watch for: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning.
Buy the JBL Partybox 100 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Partybox Club 120, which replaces the JBL Partybox 100.

Newer model: the JBL Partybox Club 120, ranked higher, rated 4.5/5, released Apr 2024. See every JBL PartyBox generation.
Pros: Quite neutral sound, pretty deep bass. Measured bass extension of 41Hz (-10dB).
Cons: A slight peak in the upper mids. Slight TWS issue where the 2nd is slightly delayed. Just as loud and slightly deeper bass than a Tribit Stormbox Blast which is way smaller with better sound quality. Discontinued.

Sony GTK-XB60: $299 Discontinued eBay
Newer model: the Sony SRS-XV500, ranked higher, rated 4/5, released Jan 2024. See every Sony GTK, XP and XV generation.
Same family: the Sony GTK-XB90 (larger model, ranked higher, rated 2.3/5).
Pros: 60W powerful sound performance with extra-bass technology for deep, punchy output. 2x 5.12” woofers + 2x 1.97” tweeters. Up to 14 hours battery at reasonable levels (3 hours at full volume with extra bass and lamps). NFC support, flashy party lights, app control for light moods. Pair two XB60s for wider soundfield. Works as mini PA system with RCA/USB/mic ports. Measured bass extension of ~60Hz (-10dB).
