Fox Farms vs. Advanced Nutrients

NEED HELP!!

I have only used Fox Farms fertz and was wondering if anyone had experimented using both fox farms and Advanced nutrients. Obviously if you go to their website or your local store they are going to tell you how great they are because they want you to spend $500-$1000 on nutes.
So does the yield and quality difference (if there is any) make up for the price your going to spend on nutes.

thanks for the help!!

forgot to mention that its a soil grow.

I have only used FF myself, ever since my second grow (noob w/MG for first grow lol). One thing to think about though is that if you want to provide the absolute max of any given element to the plant, whether it's nutes, water, CO2, etc., the plant can only make use of those additional quantities if all the other elements are optimal as well. It can't process more nutes without adequate light and CO2 for example.
I am certainly no expert, but this is info I've garnered from these pages. Makes perfect sense to me.
