What style fuel line is best?

I run Braided stainless Steel line with AN fittings for long runs that i know i won't be playing with again for a long time
EX: fuel tank to pressure regulator

Because braided stainless can fray, and tears your fingers up, i run a black nylon braided line with AN fittings for places i may alter at some point, or want or disconnect for cleaning.
EX: pressure regulator to carb bowls.
