Sigma 35mm f/1.4 MTF

Any thoughts on sigma vs samyang MTF?

I'm not really good on reading MTF, was hoping to conclude from comparing numbers, but the chart number in Lensrentals are in hundreds and the one in photozone.de are in the thousands

both are posted here :

Here is an interesting comparison image of Samyang vs Sigma 35mm, but it's in Korean

Seems that the Sigma have the edge in wide open apertures
