We have some problems with people using complex surfacingcomings in models that can be generated without using them, any onehave any pro's or con's either way. From everything that I can seeby simply planning your model before you start you can model mostthings with out the delete faces and offset faces and replacefaces, which to me just jumble a feature tree, and most of the timeif you try to make revisions to the model with surfacing commandsbeing used the model almost always fails.
