Instructing will always be better than hour building if you are paying.
The additional things you learn about aviation and people can't be listed properly.
In the UK the instructors rating costs 5k in one year I logged 900hrs and was payed about 11k. So each hour cost me 5.56 per hour for the rating so I was looking at 6k profit on the year.
Not much to live on i know but boy it was fun.
