Paradigm S8 vs. Sonus Faber Cremona M

I am having hard time deciding between these speakers. I can get each for about 6K used. I have auditioned them both at a dealer, and I like them both. However, I find it very hard to compare them given the lapse of time in between and the difference in gear and rooms. Paradigms have great reviews, but can they compare to the build quality of the SFs?
