Again I must speak for PHP here. PHP is very easy to add into virtually any web server and I find it a must now days on every web server I admin or own. Realistically none of those 5 options are as good as the PHP solution. And even if your web host doesn't provide PHP, you can install it as a CGI (which is how your Perl boards run) and even then I think it's faster then Perl. But then again I am a big Zend & PHP fan and I don't think I have a site that doesn't contain at least a bit PHP.
