ISIS vs Xspec – Confessions of a Former Xspec User
Note: Xspec is a rivalling X-ray spectral fitting package that is commonly used, but *much* less flexible. (Here is the link to one of the Xspec-bugs we found.)

Both ISIS and S-Lang are continuously developed. In order to follow up on new features, I recommend to look at the change logfiles. In ISIS' Changes.txt and S-Lang's changes.txt, I've highlighted some features which I've asked for or which I consider especially useful.
