As always nothing is simple. I have seen Robert hinges fail by pulling straight out, I think that the problem comes from having too tight a fit which pushes off most of the glue when fitting the hinge. I have used pinned hinges in the past, but have seen a lot of CA hinges in pattern over the last few years with out too many problems. But I have always found that once you have the cut off and replace a CA hinge, the new one is much harder to fit.
