Beauty is in the mind of the beholder. I don't mind honest wear on a quality gun.
I have an older CZ75 with some "ugly" finish blemishes. It was a European police trade-in import, and came that way. It shoots well and the looks don't bother me at all.
I have a couple older S&W model 10s that were also foreign police trade-in re-imports. They are functionally excellent but far from pretty- well-worn grips and bluing (I cleaned off the rust). They don't bother me either; it's honest wear and the price was right.
