I build. Usually from plans because of the aircraft I prefer. I buy ARF's also because some are great and of planes not offered in kits and its quick to replace a loss.

Some one new to the hobby can get flying quickly with an ARF. If they stay with it there is the possibility that one day they will build also.

I have a friend at the field who will not build. I personally do not have much time so that new plane takes a long time to get in the air when building.
