Ribs vs. Nubs

I personally prefer ribs, all the nubbed products I have used seemed to be painful.

however the nubbed products I have used had stiff nubs. I could imagine how a nice product that uses soft nubs (very soft) would feel nice, I just haven't found said product yet.

I prefer a ribbed passage to a nubbed passage at this time, however as time goes and I try more products, my mind may change.
