I'm a centering guy. I don't mind some corner or edge wear-- for me, that comes naturally with time. It can even add character.
Eye appeal is what I go for, and an OC card is a non-starter for me. Some cases in point in the "centering but wear" category...
All relatively cheap buys compared to their higher-graded brethren, but good centering hits the eye nicely. And some corner wear means it doesn't hit the wallet too hard, either
