Of course it's debatable to have an item restored or not... and it depends on what you're going to do with it, keeping it for yourself or sell it on.
Personally, I find it easier to sell items that had a polish or a chip removed...I do realise that any signs of age are removed with it, but it's exactly this wear that is always used as an argument, to either get the price down to a joke or not buying at all, but again, this is just my personal experience.
