This is very sad but true. I think the concept of XPS is relaly good, but I am stuck using PDFs all the time because there are no tools comparing to Acrobat today.
The way you phrase that gives me the impression you don't like the Acrobat experience. With the exception of the garish hard-coded colour-scheme I'm largely satisfied with Acrobat 9. I can't use my favourite version (V7) on my laptop because it's x64 unfortunately.
