What is the best drugstore conditioner that I should buy? (hydrating/nourishing)?

I LOVE the Herbal Essences hello hydration conditioner but I don't know if I should repurchase it (just finished the bottle), the Long Term Relationship conditioner because I want my hair to grow out, or the Suave Almond and Shea Butter conditioner. Any thoughts? (Plus, my hair is naturally very straight and thick, NOT color-treated, and I need something to prevent future damage and smooth down the frizz a little bit.) Thanks!
