PHP or mod_perl

Which one should I use for my websites? I'm not worried about difficultly, just power and performance.

i usually try to use perl for server scripts and php for web stuff, because php is so simple, but look at how much php is updated compared to perl, with php you have to MAINTAIN the fucking interpreter once a fucking week

perl never gets updated, yet it has everything you could want, i'm doing more and more in perl, but i have problems with mod_perl, it's weird to me, takes some getting used to for perl programmers, i'm using mod_cgi so far with a cgisock
