Hayward & Scott 3" elbow or AM Performance?

As the title says, I currently have both sitting.
Teh car currnetly has the Hayward and Scott fitted, but the engine is coming out to make way for a new one.
So i`m asking what would you`s recommend in using?
Also the AM Performance their is no fitting issues with it and it doesnt rattle off the Anti roll bar.
Also what ever one i dont use VSSirvine has first refusal on it :)
