Rember, samples vary. Sometimes more than between models! I have the same chart - and have done tests with it - along with the ISO 12233 charts

1- You have an excellent 18-55. Keep it! It is a winner!

2- Nothing wrong with your 16-55. It's a little sharper in the corners, but it should be.

Your test is an example of the discipline needed for such tests. Take a bow! Me, I would be strongly tempted to keep, and use, the 18-55. Why? Lighter, OS, and just as good - maybe. What does it look like wide open - or do you care?

Bow taken! Thanks for the props. I've discovered that I quite enjoy the precision required to test a lens.

Will definitely be keeping the 18-55 for all the reasons you mentioned. It suffers a little wide open on the wide end but I've found I don't shoot wide open much....so I guess I don't care that much after all!

On a side note, would love to get my hands on an ISO 12233 chart. Wow, are they pricey, especially larger versions. I saw that you can get free PDF's and print your own, but those I've found, such as this one http://www.graphics.cornell.edu/~westin/misc/res-chart.html, say they're intended to be printed at approximately 9" x 16". Is this large enough to be effective and get proper results?

Would love to hear your thought on this if you read this.
