What kind of experience does people have with the X-Men Milestones series in terms of quality?

I have been collecting the various X-titles in the Epic Collection series so far, as I really want the complete runs (I'm an X-Men fan above all else). But after having bought the Magneto war TPB, I realize how big a difference it does for me with a much better paper quality - so I'm considering switching to the Milestones series, if the quality of the paper is superior. Most X-Men storylines of the 90's where crossovers between two or more of their titles anyway, so collecting them in this format has it's advantages over the Epic editions.

I'd appreciate opinions with someone who has hands-on experience with the Milestone series.
