Standard Three View: Common or Rare?

I was wondering whether people use standard 3 views a lot? I find I often do not need all those views, and the views that do not contribute to the part I delete. This makes the drawing less cluttered but it also makes each drawing less standard to read.

Which approach do other people take?

Always the standard 3 view or only the views that are required for the manufacturing for the features of the part.
