A paper that shows off sheen and keeps a line crisp can still be awkward for everyday notes if the ink stays wet for ages. For writing at speed, drying time and smear resistance matter more to me, and the result depends on the ink and nib as well as the paper.
I judge the actual pen-and-ink combo at normal note-taking speed, not from a little swatch. A quick line, page turn, and hand sweep tell me more about daily use than a gorgeous sample does.
