The only advantage I could find of Acrobat is that it seems to open files faster (or at least the app launches faster when you open the first file). But otherwise XChange is so much more user-friendly and customisable.

You mean there is an Adobe product that opens fast? InDesign and Photoshop CS6 sure don't.

I find Acrobat
Reader the best balance for opening / viewing PDF files:
note I'm usually looking at files with lots of vector graphics and/or images in them.
It is fast, and navigation & zooming is much more keyboard friendly than anything else I've tried, including PDF-Exchange (the last time I tried it at any rate).
Seems to work fine for manuals etc with lots of text too.
[Adobe is one of my least favourite companies, so take that as high praise
for the Reader]
