pdf Question And Answer
What is the difference bet PDF File Format and XPS Document Format?
Which is better and more edit-safe? If I made a PDF file or an XPS Doc format from an Office 2007 application, can it be opened in a lower version of MS Office?
Answers
You would be better off with PDF right now.
XPS is Microsoft trying to implement a new standard, but it isn't fully accepted now.

PDF is still looks better. PDF is supported by almost all printers. With XPS, it is doubtful as with the existing printers. Both are edit safe. PDF has more to it than just printable page. It has a more dynamic file format: It has scripting, multimedia and forms capabilities.
Answer to your last question is -yes- it can be opened in a lower version of MS office.
PDF - Portable Document Format
Widely accepted, edit-safe and Reader software is FREEly available.
XPS - XML Paper Specification
Microsoft's document creator and viewer to come standard with Windows Vista
Basically a compressed xml (Extensible Markup Language). Like PDF designed to keep document layout reagrdless of the device used.
I'd use PDF for now.
