Most high end nutrients cost around the same IME.
When I first started growing, I changed nute lines a few times until it dawned on me that nutrients are only a small part of the "growing formulae".
Get your space dialled in, Air exchange, Lighting, CO2 availability, temps, humidity, genetics, grower skill. These are all more important than a nutrient brand.
Learn the parameters for each of these factors and get your grow space as close as you can to these, read as much as you can and feed a decent quality nutrient and you should have good yields. Remeber, weed costs $300-$500 retail per oz so $20 on a bottle of decent nutrients every few months isnt much to invest considering the returns or alternative.
I like AN Sensi, especially the ph perfect formulae but GH, Canna, Technoflora, Dutch Pro, Atami, Ionic are all fine nutrients and remember the plants cant read so whats in a name.
