Almost 3 million hits is nice, if you know what you're looking for. Me personally I don't know much about decompiling stuff. And just telling me Google has more information than I can look at, doesn't point me in the right direction for what I'm looking for.
I imagine the OP wanted to know if some free decompilers were better than others. What features should be included when it comes to decompiling an executable. Because some decompilers might not have adequate support for a specific language and not be able to fully decompile a program or something.
