Bias of the lens rating

The sigma 105 mm is better or equal to Samyang 85 mm at equivalent apertures (according to your review), yet the Samyang has much higher score. It seems that this is because Sigma allows high apertures to f/36 (being a macro lens), which are heavily affected by diffraction. Samyang is better, because it goes to f/22 only!?
