I'll second the LALSG suggestion. It has glycerin and protein, like the Deva gel you like. Also, as Crimson said, "mushy" hair is a giveaway for overmoisturized hair, which can be corrected by increasing your protein. KCCC and SM Smoothie are both fairly moisturizing. You might want to try Biosilk Rock Hard Gelee, which is super hard hold (a little goes a long way). It has protein but is glycerin free.

On glycerin, it's a humectant which will pull moisture from the air and into the hair when the dewpoints rise. That's fine for some, but for others, esp. if they're high porosity, the glycerin can pull in too much moisture, causing frizz and poof.
