Any thoughts or experiences anyone might have with each or both, would be greatly appreciated.
Between the Creed and the Knize, my vote is for the Creed, since (a) I quite like it, and (b) Knize Ten makes me gag somewhat. T&H Spanish Leather was reformulated a few years back, and became much less interesting, as you've discovered. It was all part of T&H's push to become mainstream, which is unfortunate. Prior to the reformulation, it was closer in spirit to Trumper Spanish Leather, which remains its original self, and is a classic in its own right. I'd probably still go with the Creed, but Trumper is nothing to be ignored, either, especially if you like old-timey scents. (That is perhaps a nice way of saying that some people find it to smell a bit old-mannish.) The Trumper is also more affordable than the Creed.
