Which domain name is better for SEO?

If you are about to find out which SEO domain ending extension is much better for our site? Is it .COM? .NET? .ORG? .BIZ? .ME? or anything else? We'll the truth is, the bes one is the firs one which is .COM? Why?

COM means communication, and it was mostly used by any webmaster here in the search engine world. Targeted visitors are always relying mostly on .COM, as it reaches out a good image both to you and your site. But I agree that all of them have the same terms in search optimizing, and there's nothing wrong to use any domain extension given here, but I would rather say .COM is the best.
