As I said in my reply to Peter, mine's as sharp as it can be. In fact, I did a little comparison similar to yours, and nearly took my 100-400 back! The 28-135 was sharper at that focal length (100mm) than my 100-400, both wide open. And, unlike Chip's experience, my 28-135 focuses faster than any lens I have, with the exception of my 50mm f1.8 MkII and 100 f2. And the difference between it and the 100 f2 is negligible.
