I love Wordpress! I started out on TypePad but the switch a while ago has been well worth it and made things a lot easier on me. As far as graphic design goes I went with Girly Blog Designz Heather is great at what she does! I think she only works in Wordpress though.
If you are serious about blogging I would absolutely recommend moving your blog from Blogger/Blogspot to Wordpress. If you're super serious... then you should consider purchasing a hosting package from a host like BlueHost.com and moving your blog to Wordpress.org.
