Two big schools: Any comparison studies?

There are two schools of late stages strategy, pushers and limpers.

Here is a typical debate

From my observation,

Pushers: Pf people, 80% of the winning population, probably more math oriented, most likely have a football star avatar.

Limpers: Flop people, fans of Negreanu, limp AK depending on situation, minority shouted at by pushers, lurking not posting in most forums, most likely doesn’t have an avatar.

I have tested these two schools but my results of course are inconclusive.

Are there any statistical studies, polls, math analysis or simulation out there comparing these two schools? Or is it only a matter of style?

If there are no studies, perhaps people like eastbay can do some simulations?

Advance thanks.
