What do I gain by going to 'performance' front end parts?

I am not having any issues with my front end, but this winter I am going to install all new parts, just so I know everything is new and will last. I get good discounts at all the parts stores. My question is: what do I gain going to 'performance' parts? Is it going to be worth twice the price and more? I looked at PST because they are offering a FABO discount. The super performance kit is $450. I can buy everything in that kit for a little more than $200 from NAPA in their top line parts. Thoughts and comments?
