IMO, Goo Gone works pretty good but leaves a bit oily film where applied. The other stuff called Goof Off looks and acts more like a really strong rubbing alcohol and evaporates very quick withou a trace.
I use both quite often depending And depending on the surface I'll chose one.

I keep all 3 handy, but reach for the Goof Off most of the time.
