You can also get sample packs from Hahnemühle and Canson-Infinity.
The Epson hot and cold pressed papers are, at least in the US, excellent papers for the price. They are very good papers regardless of the price. I don’t know what price differential, if any, there is in Europe.
But for a smooth hot pressed cotton paper, I have a strong preference for Canson Rag Photographique 310. It is smoother than either the Epson Hot Press(ed) or the Hahnemühle Photo Rag 308, contains no OBAs, and doesn't have the curling problems of the other two. I used Hahnemühle Photo Rag prior to switching to the Canson paper.
