Blogger Vs WordPress.

I've been toying with the idea of changing over to WordPress from Blogger, but i can't decide if it would be worth it.

If i did change it would probably be to WordPress.com instead of .org, even though .org offers more flexibility in the way of design and plugins i can't really justify paying to go self hosted. If it was for a business and making money it would be different  but i only blog for fun.

Another thing that concerns me is how easy it is to swap content to another platform, and keep hold of my followers.

If anyone can give me any help it would be really appreciated especially if they've changed from Blogger to WordPress. With any pros and cons.

Many thanks Ian.
