As talented as Suarez is, he will never be put in the same class or catagory as Rush who was a lethal finisher.
I don't think they are comparable, they are different types of players. Rush was a finisher (lethal as you say) while Suarez creates more on his own, but, also converts less chances into goals. Rush is more comparable to Torres, Van Nistelroy, Van Persie, Shearer, Berbatov, typical strikers. Suarez is more comparable to Tevez, Aguero, Messi (though the gap is huge) who are also responsible to create.
