vrs x vs bbk x Which one and your reasoning please

[32V10TH]

I have bbk lt's and I want an off road x but cant decide. It seems the vrs is more popular and Im just curious as to why. What are the differences?

I have a vrx x pipe for stock manifolds and love it. polished stainlesss, no fitment issues, with the vrs x the exhaust gas's never cross paths like the bbk and from videos i have seen it results in a smoother sound if that makes sence.
