Considering Migration

I was planning to change a new theme for my blog host by Blogger, then started to have this tinkling feeling of migrating my blog to WordPress, after messing around with themes on both Blogspot & Wordpress i decided to migrate all my post to WordPress....I'm still undecided about this migration...will give it a week perhaps.for me to figure out which host service i prefer! My apologies if its confusing...but i rather have both simultaneously to compare...
