Motion Blur settings for Animation?

So, I’ve been working on a animated short film for about a month now. I’m finishing up the rigging, and soon I’ll be doing animation. I was wondering about the effects of Motion Blur. My short film is that half-realistic, half cartoon style (like Agent 327) Does motion blur make much of a difference? How much does it affect render times? What settings should I use?

For me it seems to work very well if you are working at 2k or 4k along with 24 fps.

The Animations smooth out better with camera transitions along with other effects.

Best of wishes on your project!
