The extractors are hit and miss for me. The glue trick sometimes works but sometimes makes it worse. Drilling it out works, but requires another set of work to reattach and is a bit scary to perform.

Before doing those, I'd recommend jamming a rubber band on top to gum up the hole, then trying to unscrew it through the rubber band. It works often enough I this before I do any of the other options above. Quicker and less destructive.
