It's not much trouble to create the thread. Two sets of supporters got tetchy with each other and so want to argue for a season, which they will get to do, and if their teams are about the same quality at the end, they will get to argue some more. The thread would therefore serve its purpose.In reality the teams would be about the same - I don't disagree. But I just think if you go to the trouble of setting up the thread and have all the banter that goes with it during the year there should be a team that comes out on top in the end for the purposes of the thread.
And on your second point it wasn't the case with Blues/Pies thread. One team made finals and one didn't and it was still not clear cut. Like I said I'm happy with any metric as long as it's established before the season starts and kept the same throughout the year.
If there's a clear winner then great, it means one set of supporters get to troll the others for at least an off season. Usually that's what would happen. Collingwood and Carlton supporters instead have been at a bit of a stalemate after 2024, which is why the back and forth over who was better continued.
