If you are running INSANE horsepower then you need bigger fuel rails.

Otherwise the only gain that I know of is that the larger rail reduces injector-to-injector pressure-pulse interference (ie fuel presssure harmonics).

However, the stock rail has a harmonic damper to deal with this issue.

I use the stock rail FWIW with 75 lb/hr injectors at ~700 RWHP.

I thought about getting some for the appearance mod also lol. They look so much better then stockers unless you get the stock ones polished or something.
