I prefer FSG, it's my HG when I use gel, but the things I love about FSG are probably what some people don't like. I love that it's lightweight, has light hold, is not crunchy, and doesn't make my hair clump or overly defined. I have fine 2a hair so if I use too strong of a gel, my hair just looks hard and stringy. FSG-I usually use Jessicurl RR which is basically FSG with mag sulfate- gives me just enough definition, frizz control, and curl enhancement, but it is definitely a strong hold gel at all. I'd actually call it more of a jelly. Biotera, in my experience, is light but is still definitely a "typical gel" if that makes sense. They're both good, it's up to your preference.
