Both of my garters have a "don't mess with me or I'll gum you to death" attitude. They're fun to watch, not so much to handle.
Kings are fun to handle without the defensiveness. I only have one female that has every bit me though, and you can tell when she's "foody". A cotton ball soaked in white vinegar waved in front of her nose is enough to get her to release when she decides your pinky is really a pinkie...
