However, an installment (auto) loan with a 50K balance is viewed much more favorably by credit bureaus than a revolving (credit) line with a 50K balance.

If you're worried about your credit, the credit bureaus don't like having too much revolving credit open at any one time. On the other hand, they don't like it when you close accounts either because it negatively affects your debt to credit ratio.
I never understood this either...
