The original is still the best
I have had the backnobber for just about as long as they made them (could be 20 years).  I decided, since I rely on it daily, that a backup made sense.  At first I tried a different brand, one with many nobs coming off it.  I found this style very hard to use, not intuitive, and the extra nobs just got in the way.  So I returned that one and got this one again.  For me, it really is easy and intuitive to use, and helps applying trigger point pressure in my back, shoulders, and neck.
