4" Superlift vs. Tuff Country - Opinions please!

[Sooner1970_K10]

Howdy! I am in the market for a 4 inch suspension lift: springs all the way (no blocks)!! I have heard good things about both the superlift and tuff country lift. What I want to know is which will ride better i.e. straighter, more like a stock ride and have less wobble/wander. Basicly be better suited for highway driving and less dirt crawling. I realize the superlift seems to run around $150.00 bucks more but price is not my primary concern. Has anyone had both type of kits? Any comments or advice for a new 4x4er. I want to stick with a simple 4" lift so I dont have to worry about drivelines, brake lines and whatever else that might have to be changed. This is for a 1970 chevy k10. Thanks!!
