what is the best resource editor for delphi ?

Both the first two aforementioned utilities are good, though have become a bit dated, and I'm not even sure of their current status. The third I've not tried.

HOWEVER, since this is a very legitimate question, I propose you posture it on a site that gets more wide-spread exposure, such as Stack Overflow (no link provided, go find it if you really don't know what I'm talking about). This seems more appropriate for that, than for this... as it is a general, legitimate, development question.

The best was Resource Hacker

For now i think there is no resource editor that can handle Delphi XE2 executables, specialy 64bits and FireMonkey (correct me if i'm wrong).
