i can try to compare.
i have accounts in elal matmid and continental one pass.
i need 1400 points to get a free economy class ticket to bangkok at elal and 80000 miles to get the same at skyteam.
i have a leumi platinum card, what is allow me to earn 1 elal point for 350 shekels=82$
i have also amex international dollar card that earns 1 continental mile per 1 dollar spend.
so to earn a free ticket to bkk i need 490000 shekels= 115000$.
to earn a ticket to bkk at onepass i need to spend 80000$.

so the difference is around 45% in the behalf of onepass
