Which hurts more a bumble bee sting or wasp sting

First, there isn't a single wasp species, there are many species.

The Tarantula Hawk is a large wasp. It's sting is "considered to be the most painful of any North American insect". It has been described as you want to die, but can't.

Do a Google search on "Tarantula hawk sting".

Wasp stings. When a bee stings the stinger breaks off in your skin and it dies. This does not happen with wasps they can sting multiple times instead of only once.

I think they both hurt pretty bad. I guess it depends on your tolerance for pain and I have none.

well wasps are big and can sting as many times as they want
bees are small only sting once and it kills dem...

I assume it's wasp.I've never been bitten by either so I don't know.
