What I find about de-fishing is that it sometimes will smear the corners. I went from a Sigma to a Canon lens and that aspect improved, but it's still an issue. I'll bet that your 17mm TS-E is going to be way, way better in the corners.
My software will correct the 17mm TS-E, so I'm really tempted to get it. I use my 15mm so much, I think that I'll go crazy with the 17mm. I may borrow one from CPS to check it out.
