Blogging

I'm hoping someone will read this and explain things to me. I currently use a free template and write my posts using blogger. Howvever with the new year coming up and Albie being born I was looking into mixing things up a little. Has anyone changed over to Wordpress from blogger? What's the best? I'm also thinking of purchasing a template design from etsy, does anyone have experience of this? 

Is there a way to keep my blog lovin followers? 

Please help an a blogger out!! 

Thank yooooou :)
