What are the advantages of nickle over brass valves???

Hey guys im fixin to order some asco valves. My question what is the advantage of buying nickle over brass...  Im not building a show car im building a driver.. So reliabilty is much more important than looks....  Let me know what your experiences have been and what yall think!! Thanks yall....

There's no advantage....the nickel valves are just nickel plated brass valves.  Same valve, one's just shiney
