See, I was the other way around. The original one upset my skin but my skin adores r/o
I've been using this one from Ecotools+
I liked the EcoTools when I used it. It was firmer than Beauty Blender but not too hard.
These two Ecotools brushes do exactly what you want (at least for me)++
Not sure about "best," but this one is great and reasonably priced ++
