There is a lot of information already in this and other forums on stock and finish, so I will be brief.
Cards from different makers feel different. USPCC has a distinct feel, EPCC has another feel, and so is Cartamundi and others.
Most cards from the same maker feel similar, especially for a beginner who has not develop the touch sensitivity. With time your hands become more sensitive and you can feel the differences in various stocks from the same maker, as well as differences in the same stock and finish from various print runs. Even when the maker is saying he is using the same stock and finish, there are some variations in paper thickness, stiffness. Such variations are inherent to any process. Also, paper and process used by a maker changed, optimized, with time, leading to some differences.
It is very difficult for the beginner to determine from description how a deck will feel. This gets frustrating since even with reviews telling about the stock and finish, reviews are never detailed enough to know for sure. My advice is to get various decks, of various stock and finish, from various makers, use them and see what you like.
