Nutrient Challenge botanicare vs. cutting edge

I just purchased my nutes for this grow and i am going to do a side by side with botanicare and cutting edge nutes. I am starting some pineapple dream from seeds and most likely going plant in a soil or soilless medium. I still choosing soil so if any one has any suggestions or comments let me know
