Exhaust tips. Chrome vs Stainless

I need to replace the exhaust tips on my 68 formula S barracuda. I'm looking for reccomendations and/or warnings for chrome or stainless. which do you prefer and why?
No matter chrome or stainless make sure you get the correct ones if your present exhaust is pretty original. The 2nd gen Barracuda dual exhaust chrome tips are not straight, but are angled up.
