I am going to throw in a slightly different take on this. Adding fish immediately only works if your plants are growing immediately. For most of us, that isn't true. I don't set up tanks using 100% plants from my other tanks, I have to buy some to all of them. That means shipping, adjusting to new water parameters, me being newbish and having to figure out how to get each plant to grow, etc.
What that translates to is a lag time between setting the tank up, and having a healthy, growing NPT. If I add fish before that, I am fish in cycling (to be avoided at all costs, IMO).
I wish I did have enough tanks, and extra plants, to just start tanks from my stock.
