From several tables I played on, the cheaper stuff (not Champion but the more generic brands) have a rougher feel to it than Simonis and also have a stronger smell to it. A pool hall near me redid their tables with some Chinese cloth and the whole place had that plastic chemical smell you get from some products, and the tables felt almost like what a sharkskin feels like, not quite sandpaper but rough. That was not the only place that I ran across with with, but they did a bunch of tables at once so the smell and feel was really noticeable there.
