I almost ended up getting the copper-nickel tubes for my fuel lines... and kind of wish I would have instead of stainless for ease of bending & sealing.
Average internet opinion indicates that it's superior to plain copper with regard to bending fatigue and strength.
There's an interesting table at the end of this webpage:
