What's the best vocal remover you've used that doesn't destroy the instrumental?

I've been testing a few vocal remover tools recently for creating karaoke tracks and remix practice.

Some AI tools do a surprisingly good job, while others leave noticeable artifacts or make the instrumental sound thin.

I'm mainly looking for:

. Clean vocal removal

. Good instrumental quality

. Fast processing

. Works well with pop and rock songs

I've tried a couple already, but I'm curious what everyone here is using these days.

Are you using desktop software like UVR, browser-based tools, or something else?
