Which is the best EXE/PE editor?

[chants]

Note that CFF Explorer is free yet has not been updated in a long time though it hardly needs it given only modest changes to PE so its still a great utility:
Download the Explorer Suite
Current Version: III (18/11/2012)

Of course PE Explorer is also worth a try (free trial only though):

Or maybe even Professional PE file Explorer (PPEE) since its free

If you are just after editing the resources of the PE file of course there are better specific tools for that purpose than any of these. A separate discussion though...
