Who's "Life Biograpghy" would be a more interesting read Yoda or Palpatin/Sidious?

I would want to know Yoda's biography, as long as his species and homeworld were left out of it...

it'd be a bit hard considering it his biography

You don't have to start it with his birth.

If anything, I'd have him be found in some accident, like 'lone survivor of a space pirate raid' or whatever.
