In mjardeen's defense, the OP contradicts itself. He does put out the suggestion of the 16-35, but also says he want's something wider than his 15-85.
I don't find it contradicting to compare the IQ of two lenses of different focal length ranges. MTF, colour aberration, and vignetting, are all examples of things you can compare. You can even compare the IQ of a 14mm/2.8 lens to a 400mm/2.8, even if there of course are very few situations where you can substitute one for the other.
