> I would add Ordinary Least Squares (It may be the same as your SS), Weighted Least Squares, Maximum Likelihood and Restricted Maximum Likelihood.
> These four methods are available in the function likfit of the package geoR.
> I've been using it a little bit and I think sometimes one method works better than the other one but I don't know the clues for making an a priori decision!
