Digital BW, The Print

I was looking on their site trying to figure the difference between 
these two products (aside from the 5 gm weight)

http://www.premierimagingproducts.com/premierart/Fine-Art-210gsm-Dual-
Art-Matte/PremierArt-Fine-Art-210gsm-Dual-Art-Matte.htm

Anyone tried both and can say something about the feel and look?
Is it the surface texture ?

A local dealer carries the 210 but it was the 205 that was actually 
recommended to me

thanks
Frank
