Why is the Classical Sicilian so uncommon?

When I go over master games, I find lots of examples of the "Classical" Sicilian, including Sozins, Richter-Rauzers, etc.  But in my own tournament games, I have only faced it ONCE - and that was against an FM in a rapid game (I drew)

In my experience when people play a Sicilian against me, it goes as follows:

Najdorfs (50%)

Dragons (25%)

e6 lines (kan/taimanov) (15%)

And the rest are generally a smattering of Sveshnikovs, Okellys, etc. But the classical is super rare for some reason, at least with the opponents I usually face (1800-2200).

Anyone else experience something similar?

just fashion.

The Richter-Rauser is supposed to give White easier attacking play than other sicilians in which White castles queenside. I think it's one of the reasons why a lot of people went to the Najdorf. How relevant this is to non-professionals I don't know.
