Like some, don't like others
I'm one of those people who buy paper pads and pull out what I want and donate the rest. Part of that's practical since I have drawers and drawers full of paper already. But I've also learned what I will use from having done collage for 20 years. This is obvious grunge paper but don't let that stop you from other creative uses. Science fiction, steampunk, city travels, downer emotional themes, etc. These papers can also make great photo mats or accents not because they read literal but because they have more random patterns and colors (as opposed to the usual strict repeating ones). Certainly not for everyone.
