Climate control does not have as much hold, and my hair feels softer when I use it. It smells a bit perfumey, but I like it - think of some of the shampoos from the 80's.
Tress F/X has a bit more hold, dries a bit crunchier, and smells like clove.
HTH a bit...If I had to choose between the two, I'd go for the Climate Control. There are way cheaper gels on the market than can do what Tress F/X can do. However, Climate Control does have dimethicone toward the bottom half of the list, if I remember correctly.
Hair Type - medium to fine texture, high porosity, lots of it, type 2b/3a
