When people are building or rebuilding, they might start out with a company like Credit One. But they're going to follow up with new (and better) cards soon after that. Even if Credit One is your oldest account, your subsequent accounts aren't going to be that much newer. Your oldest account age and your average age of accounts aren't going to be affected by enough to matter. Getting Credit One out of your hair is going to matter a whole lot more. In this case, your sanity is the overriding factor.
