Best win32 decompiler?

REC is a portable reverse engineering compiler, or decompiler. It reads an executable file, and attempts to produce a C-like representation of the code and data used to build the executable file.

Yep, I've got that one. But is this the best one?

What does "best" mean in this context? It works, what else do you want? I don't think decompilers are a lot of use myself.
