And a complement in answer to what you say : Blower fans with special designed bladed which make them more efficient than the puller equivalent, have just been designed to increase the efficiency of a blower fan because some applications do not have enough room between the engine and the radiator to install a puller. So it is totally normal that these kind of design exists, but it doesn't make a blower set-up more efficient or generally preferable to a puller set-up, for the reason exposed here and the other thread.
