Do Roundell rubbers have less spin than Tibhar Genius?

[SpinPi]

I just changed my rubbers from Tibhar Genius to Butterfly Roundel, and to me it seems that Roundell rubbers has less spin the Genius or maybe is just my impression from changing the hardness of rubbers (soft to hard with high tension)

Genius is pretty grippy, Roundell is more of an allrounder rubber imo
