A rubber fuel line is always the easiest to replace. Just make sure you use fuel line so it will not be melted by the gas. And ziptie the line to the frame so that it will not rub up against it and wear through.
Rubber fuel lines are way easier to install, but they do not last as long. The metal fuel lines, in my opinion, are for show. What you could do is get the rubber lines that have the, I think it is nylon, braided outside. They are less expensive, easy to install, and durable.
