Hi.
Ive used both families. I will guve my 2 cents, even though I cant answer your question...
GHE has been my hydro go to and has not failed. Used it for 15 years or so.
Bio bizz I used in comparison with biotabs family and those crops were the best tasting crops. It was in coco. Bio bizz test lasted 2 years.
Both are great, both can be used with soil. If you do everything right, tastier crop in soil will be with organic nutes, biobizz in this case. Crop wise, you get good or bad results with both.
Add fungi in the soil too.
