I played 4 string for 14 years before getting my first 6-string. I've been playing 6-string now for 16 years and can't ever imagine going back to a 4, I simply wouldn't be able to play the stuff on a 4-string that I've written on a 6, it would be impossible. So, in the end, it comes down to playing the instrument that is right for what you need.
No guitarist would ever want to play a 4 string guitar, they would feel limited. I feel the same way at the idea of playing a 4 string bass, there would be so much of what I do that would get thrown out the window.
