I'm assuming you mean skin staples here beejill, so if I'm wrong please ignore my answer.
I've had staples myself (the last time was a very big abdominal surgical wound) and coming out they didn't hurt at all. If one was a bit stuck it just stung a tiny bit as it came out, but I found them much less uncomfortable than stitches.
They have a little metal staple remover that slides under the centre of the staple, and when pressed it flattens the staple out so it pops out of your skin. Easy peesy!
If I ever had the choice, I'd always have staples now over stitches now.
