Plays Well With Others...
I love WordPress...but it's completely different than Blogger, file-wise...when it comes to designs.
If you wanted to give it a shot without any commitment really, you could set something up at Wordpress.com - which is free. That would give you a feel for the themes available and what the admin/posting/management "dashboard" is like.
Having said that...and having had to "relearn" it twice...it's not that tough to pick up.
