It's far, far faster. I can edit multi-gigabyte files without thinking much about it, my last attempt to open a 10GB log with Emacs did not go well.

I also think it's got much better integration with Windows, though I can't point at anything in particular. (Its integration on MacOS is less wonderful).

It also helps that its defaults mostly line up with my own preferences in an editor, though this is highly subjective.
