I have used both and they are different. I use green on all my trucks, they work extremely well. On race cars, yellows are the best. Big difference is green will work on all conditions, cold, hot, etc. Yellows will work lousy when cold and can make a lot of noise, but once they are heated up, they retain that braking friction at extreme heat. They are a racing pad, and designed for that environment. Driving around town they can squeal a lot as you will never get close to the repetitive hard braking-pulling-eyes-out-of-sockets conditions where they are designed to grab. And they do grab like hell.
On my 80, green 7000 series work best, the heavy duty ones, not the 6000 greens.
