Which is best(speed/ease of use/stability)

Why does Fast cgi exist when you can use Apache::Perlrun instead of Apache::Registry to run unmodified CGI scripts?
Should we all be writing Fast cgi scripts so our scripts are not limited to only running on Apache?
Is vanilla CGI(mod_cgi) going to be deprecated and is there any reason at all for using it instead of mod_perl or fast cgi.

Or is this another case of more than one way to do it.
