both have different flavors and even lays have few spicy flavors.its a matter of interest and likeliness.i like all flavors of lays.even kurkure is not so bad.sometimes during journey i prefer on kurkure as its a better time pass.
I prefer Lays over Kurkure since Lays is good and worth it to eat. Plus the fact that i didn't know the other product you are saying, maybe it is unavailable here in our country.
Both are best.sometime when i complete my breakfast i just eat 1 lays full packet,and every afternoon when i go to market i eat kurkure.so both are best for me.
