You have an emotional attachment to one of the teams and that probably clouds your view of the actual quality of the play.
I think it's your emotional attachment to England and your agenda to grow international RL that has clouded your judgment.
I hate SOO with a passion, I strongly dislike Queensland and I hate NSW with a passion that only a Canberran displays (of course this is in the sporting context). The only way I could become a fan of SOO is if it was to be expanded to include the ACT, which is almost certainly never going to happen.
But even I, a person who would like to see SOO fall into obscurity more then most, will freely admit that SOO consistently produces the highest quality of RL in the world.
Every now and again an international of similar quality to SOO will pop up (2013 RLWC Eng vs NZ semi comes to mind), and obviously not all SOO games are of the highest standards, but overall SOO is the format that produces the best quality of RL in the world the most consistently.
