Subject: style choice

A style question for the community ... which of the following do you prefer, and
why? Or, if you prefer some third version, what is it and why?
  
  def degree
    return @degree if @degree > 0
    @scopes.each { | field | @degree += field.length }
    @degree
  end
  
  def degree
    @scopes.each { | field | @degree += field.length } if @degree == 0
    @degree
  end

I'm giving the best advice I have. You get to decide whether it's true for you.
