And even better yet....the expensive one is a lot less likely to stick shut and put excessive wear/destruction on your engine and turbo!

I've got an HKS SSQV, But Tial, Synapse, Greddy, HKS, are all quality products. Sound can play a big roll in what BOV you go with as well. I'm a ricer at heart so I wanted more than just a gush of air sound

On my latest build, I'm using Synapse BOV and Synapse wastgate. They are supposedly the "latest and greatest"....even better than Tial....but only time will tell if that's true.

you don't want to use a BOV on a procharger at all, you want a BPV. BOV's are not recommended for a procharger.

The new Tial Q is about the most badass and high flow BOV availible, and yes you can use it on a supercharged car, just be sure to get the lightest spring. They work great and sound awesome!
