Digital BW, The Print

I haven't used this Espon UltraSmooth Fine Art Paper (USFA). But looked 
at its specs, it seems close to and between Moab Entrada Natural 190 or 
300mil.

My questions are: How good is this paper for B&W or color printing? For 
100% cotton, natural colored matte paper, are there any better choice?

Thanks,
Philip
