I would encourage you to ask the opposite question: " Is there any reason to run OSPF over IS-IS in the SP core?" And the answer would be... probably not. There is not really a good technical reason to run OSPF over IS-IS in the SP core. You might have some aesthetic considerations such as wanting the SP core to run the same protocol as something else, despite its limitations.
Just to add to everything that Jimmy said, if you've got the time to do an in-depth side-by-side analysis of the two protocols, I strongly recommend the book "OSPF and IS-IS: Choosing an IGP for Large-Scale Networks" by Jeff Doyle. I can't speak highly enough of this book...
