Template

So I want to change my blogger template.  Do any of you have suggestions or thoughts on what you like looking at best when visiting blogs?  Is there a type of font you prefer?  How about background color for the text?  Or background color for the blog itself?  Any type of themes you like a lot?  How about anything you absolutely hate?

I'm looking at these themes, any thoughts?
