Maybe, just a wild guess, more people who played this game are males and identify better with male characters. So they chose Leon first. Then, after completing it, had no desire to play it all over again from a different perspective.
I can tell you I played the original once, beat it with Leon, and never picked it up again. I had no desire to play it from Claire's perspective. Just was not interested in playing it through again.
