OK it has been said many times . . .
It depends what you are trying to do.
There are some excellent instruments that run in Kontakt : Spitfire Edna is one that I am looking at.

Also, Spitfire LABS(Free) and Kontakt player(free) have some interesting textures definitely not a waste of time
These have inspired me to produce music that I normally would not think about.
