I make three hair gels, Simply Hair Gel, Simply Defined, and Simply Flaxseed. The difference between the three gels is in the strength of the hold. Simply Hair Gel has the lightest hold (and comes in a trigger spray bottle), Simply Defined has a medium-strength hold and is also flax-free and Simply Flaxseed has the strongest hold, though it is still a medium hold hair gel.
I typically recommend Simply Hair Gel for thin or lightly wavy hair. Simply Defined and Simply Flaxseed Hair Gel I recommend for all other hair types depending on personal preference.
