I was able to grow huge colonies from frags with LED. But when you want the coverage and brightness, you need to spend big $$$. This is where the line was drawn for me.
Maybe LED's have too many options and not enough testing. You can easily tune yourself out of an acceptable range for your corals. I would invest in an LED again if there were limited presets with static height/coverage requirements. Don't over sell/rate your product and give the customer an educated recipe for optimal coral color and growth.
