What hurts worse A bee sting or a wasp sting?

I was mowing the lawn and got too close to a wasp nest and got stung once. ( I got away quickly) and I am about to do my backyard now where there are a lot of bees. I mean I've already got stung by the wasp and it hurt like hell. So does a bee hurt worse the same or less. (Im not going to test it out) I know they both hurt and a bee isnt gonna feel nice but Im just wondering.
