I don't know, I just think we have different opinions on it, which is fine.
I just know that the dirt route can be a big mess for a beginner, even if they've done their homework. It's not rocket science by any means but I do know some that regretted going that route for various reasons, algae, super dirt clouds anytime something on the bottom moves, digs, etc.
It's definitely an economical and extremely effective method, though.
So to a beginner I'd recommend something simple like ecocomplete, just dump it in, add the clarifier and you are good to go, no dust clouds, no mineralizing period, no potential algae period, no capping, it just seems like a simple and effective route to take when you are just getting into the scene.
I just don't want to be mentioned in the grumblings of a person scooping the muck out of their tank in exchange for something simpler, that's all.
