Basically I'm trying to find a blog for a website, and security is the highest priority in our case. We don't need any features that I would imagine are special. Wordpress was our first idea, but its reputation precedes it, and though it may have cleaned up its act lately, I'm not seeing much solid evidence.

I get the impression that Movable Type (at least the Perl version) has a much better reputation for security than Wordpress (historically at least). I'm not sure I want to take a chance with Wordpress at this point, but is there some objective source I can got to to back up (or counter) the notion that MT is at least among the best? Secunia doesn't recommend using their stats for comparisons, and securityfocus.com doesn't have stats at all that I can see. Searching here http://web.nvd.nist.gov makes MT look way better than WP (at least in 2007), but this site was referenced by MT's own page boasting about their security, so I don't know how relevant it is or how seriously people take it.

Any suggestions on sites where I could/should make a somewhat objective comparison?
