The answer, is unfortunately, is very few of each.
Everyone seems to get tied up in the summer vs. winter debate and, to be frank, there's no right or wrong answer.
For me, this is a Rugby League issue, not a summer/winter issue.
Everyone is quick to point the figure at the RFL selling 'the summer dream' and also people saying the game is dead in winter. The truth is, summer works for some clubs (such as mine) and winter works for others.
I think a major factor is that we have both summer and winter seasons so easily accessible for clubs. If one isn't working, they'll simply forfeit their fixtures and jump ship to the other season. This isn't good for anyone
