I'd go for WordPress. I'm using this for my website and while coding is kinda mean, the service itself is great.

Then again, I have a huge issue with blogger, since their service simply sucks. Two years ago, someone was copying the content of my journal over at blogger.com, and when I asked them to investigate the case their answer was basically "Get yourself a lawyer, but don't bother us." :-/

I really like WordPress. It's nice, easy (more or less) and you have a trizillion of option when it comes to add ons. Blogger... well, see above.
