Question about aftermarket elbows?

[Cerwin Vega Fan]

I need a new elbow and I was wondering how does each one flow. I was looking at the 1LE one as a solution to my elbow problem. I was wondering does it flow just as good as the Trick Flow and Vortech elbows? I like the 1LE cause it looks stock (sleeper look I guess) and it is lighter than the aluminum elbows.
