The one I posted has an inner roller which is actually a dense foam. Great for certain things. The outer, has (or should have) a plastic inner with the knobbly coating on the outside, in the same way that the other brands have. Personally, I find the larger pointy knobbles on certain brands to be of no value at all, other than feeling kind of nice. For me, they don't do the job any better.
Certain brands will cost more because of the name. The type I posted is fairly generic, but whatever you buy, I would encourage you to get one with an inner roller as well as an outer as they have different uses. Perhaps pop to tkmaxx and have a feel as they always have some. As far as my experience goes, they are pretty much of a muchness, with a small degree of "more money means better". But as always, think about who you are (a regular Jo buying for occasional home use or are you equipping a gym?), and what you do (powerlifting like yukurin, or just riding your bike and stuff, getting a bit stiff/sore?), and go from there. Good luck and happy rolling.
