How bad is getting bitten by a Gila monster?

I'm from Arizona and managed to successfully catch a couple of these on different occasions without it ever biting me, placed it on a tank, feeding it, keeping it as a pet. I like them even though they're venomous but not fatal. They're actually one of my favorite animals.

Let's say it were to eventually catch me by surprise and bite me one day (even though I'm too fast for it), I know you don't die from it but on a scale of 1-10, how bad is it to get bitten by it?

To me it's not a monster. I actually see it as a beautiful lizard, nice coloration.
