I've had the opportunity to run numerous line-ups, including AN products, and it ranks very low on my list, when considering all the major factors, price, ease of use, yield, end product quality, etc.
Being a lazy hydroponic grower, I've found that Cutting Edge Solutions knocks pretty much every other line-up out of the game. I haven't checked pH in over a year, I don't check ppm, I don't even flush and rinse my reservoir ever 2 weeks, just fill with water every 3-5 days and feed every 2 weeks; plants stay green, healthy, grow huge, and flower profusely. On top of these wonderful properties, this company is also a small, American based business in California that have been developing their formula for a specific crop for many years and it shows. Their line-up is also one of the most economical to run, granted I run my units always between 1/4 and 1/2 strength, so I get even more mileage for my dollar.
As a farmer who has been doing this for more years than I'd care to count, I'd recommend this line-up to anyone confident they will be more than happy with the final results.
