Personally, the jar is better than the squeeze tube and the roll on. The consistency is a better and it last much longer. I find the tube is thinner and requires more applications. I live by Carmex. It's the only thing that keeps my lips moist. Great product.
I think it depends on how you like to apply the product. I hate getting this on my hands, so I prefer the squeeze tube, but some say that the formula in the jar is a little thicker, so it depends on your preferences.
