Which parts?

Hey y'all, I wanted to get your opinions on Moog vs. P-S-T. I like P-S-T, because they offer a whole front end steering kit. I would also like to know if you guys think the polygraphite bushings are worth the extra cost. I am looking at buying the "Polygraphite performance super front end kit" for $440. The "original performance super front end kit" is $380, so not a whole lot of difference as far as price goes, how about performance?
