Some papers have a little more surface texture then others that can effect the impression of sharpness. I think Ilford Gallerie has the most. The sharpest paper I have ever used was the now discontinued Zone VI graded papers. Very little suface texture. It was a great paper. Now I think the best paper on the market is Oriental Seagull graded papers. Deep rich tones with excellant toning abilities. I do not use VC papers. They seem to lack the ability to give a real deep night sky like black that you can really look into. I have never seen any of Ansel Adams books where he printed on VC papers. Though in his darkrrom book, he has a photo of an old style VC head.
