Are R-15 and R-11 very different in term of energy savings?

I have two different doors with different R-ratings for energy efficiency? Is there really a big difference in energy savings between a R-11 and a R-15 rating?

Not really, but if you are going to choose which is more officiant, then go with the R-15
