Short answer: the W-King T12. It ranks #21 of 46 party speakers by sound quality (rated 3.8/5) at $439 and is still sold new; the Sony GTK-XB90 ranks #42 (rated 2.3/5) and is discontinued, so it is only an option used.
The W-King T12 is the better-sounding, longer-running choice. A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. It is rated for 25 hours of battery against 16 for the Sony GTK-XB90. It has an adjustable EQ, which the Sony GTK-XB90 lacks. The tradeoff: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound.
The case for the Sony GTK-XB90: Deep punchy EXTRA BASS technology for party use. It supports LDAC Bluetooth, which the W-King T12 lacks. It links with other speakers (Partychain up to 100 speakers), which the W-King T12 cannot. The catch: Bass is muddy and not deep, weird midrange peak, rolled off treble and overall strange tuning.
Buy the W-King T12. It is rated higher for sound quality, and the Sony GTK-XB90 is discontinued, so it is only available used.

Pros: A large, capable karaoke-party package with dual 8-inch woofers, independent bass and treble controls, mic and guitar inputs with echo, USB and microSD playback, USB-A charging and TWS pairing. Its claimed 25-hour battery and trolley-style form make it practical where high output matters more than compact size.
Cons: Reviewer comparisons find the tuning boxy and less clear than the better-ranked party speakers, so its size and quoted power do not automatically translate to refined sound. It is a 15kg, 75cm-tall speaker with no water rating and no app; the physical tone controls are its only meaningful way to adjust the sound.
