You can turn on "Reduce Motion" to change it from a slide to a fast cross-fade.

I ultimately stopped because the trade off is not being able to see web animations (or most any animations in the OS) most of the time, which isn’t ideal as a web developer.

Looks like there's a Chrome command line flag to override it: `--force-prefers-no-reduced-motion`

That is just an illusion. Time is the same. Instead, you need to add abstraction on top of CMD + Left/Right keybinds to get fast movement between spaces, for example.
