I've never used the koils by nature products, but I do have the DB pumpkin seed condish and I love it. It is extremely moisturizing, and I've never had any issues from the protein. It's a very thick consistency, but still has decent slip. And the smell is soooo yummy.
That being said, it sounds like the other stuff may be a better deal (35% vs 25%), plus you already know you like the brand. I would go with the Koils by nature (more bang for your buck), and then wait for another CurlMart sale to pick up the DB condish. But if you do decide to get the DB pumpkin seed condish, you won't be disappointed.

My favorite brands are Kinky Curly, As I am, Curly Kinks, Curl Junkie, and Darcy's Botanicals. Also love sealing with oils (loving argan oil right now) and styling with jelly products (KCCC is my current favorite). Mostly trying to keep it simple!
