If you ever get a chance to try "carolina reaper" peppers I strongly suggest giving them a try. A friend grew some and they have amazing flavor imo. Very hot but retains lots of flavor when dried. If you can grow them, even better!!
It is a brutal pepper and only the truly exceptional, probably <0.001% of people could honestly say they enjoy it.
I do suggest to someone who may want to try them to use very small amount in cooking so they can enjoy it. I wouldnt want the experience spoiled because it is super hot.
Whatever you do do not touch your eyes etc even after you wash your hands!
