Performance difference would be hard to compare unless its a really faulty design. Each engine is different, so no piont to compare just on tbe itself.

On the other hand, Longitivity and fitment r easier to measure. I have seen xforce, norm butler and invidia, I would recommend invidia with an add on divorce plate like their USA version. Race torque can supply and install them. They all perform similarly on dyno. But Norm is quieter and less drone on fwy. But my norm down pipe failed after only 70000km. Might be an isolated case.
