I currently use Blogger, but self-host on my ISP's server. I agree that it would be safer to control my own pHp too. I still like WordPress, having used it before, but with extra control comes a bit of extra work. With a quick check I found an import plug-in to bring Blogger posts into WordPress, perhaps there are others. In a comment to that post, someone else suggests that Blogger can export feed-like xml that WordPress can import directly. If your post is about keeping with Blogger but shifting self-hosting to a different server or domain, commentators in Blogger Help say that it can be done relatively painlessly.
