Alternative To Bondo?

I have done a fairly decent amount of bodywork in the past with good results using Bondo for small areas. I know good body work is mostly all in the work.
I was wondering if you guys have used any other brand of "Bondo" and thought it lasted longer, or was easier to use etc. etc.??? One local Napa carries a great selection of body supplies, anybody had good results with "Napa" bondo?
