I think that whoever takes it as a religion is not a true flight lover is not having a real hobby. I feel there is too much fear of comparing two sims and its products. The important thing is not to insult anyone and not to lie about personal matters, however it is not possible to ignore the fact that some sims have better graphics or a better campaign etc.
For me, the comparison is useful only if you look to the future. I am not on anyone's side, I simply follow and hope for those who continue to progress. A sim that remains stationary, dies.
