I think it's up their the ending i would argue was the most epic even when in comparison to 1999 and 1997. In those games the Knights began to get on top of Manly in the last 5 minutes they nearly won it with a field goal the play before and the scores were tied. Melbourne seemed to have a lot of momentum against the Dragons.
Second half yesterday it looked like the Cowboys had blown it with the Linnett chance Brisbane were defending brilliantly and the Cowboys weren't really looking like scoring apart from the Linnett play. On the last play of the game Granville throws a poor pass to Thurston who nearly get's tackled twice and runs 10 metres backwards he passes it to Morgan who pulls off arguably the greatest play Grand Final history that last moment they didn't even look like scoring until Morgan slipped that offload they didn't have an overlap it wasn't like a certain try but they still scored and that for me is why it was the best finish ever it came from nothing.
In terms of best ever i think it might struggle to hold up quality wise but that is mainly for the second half the first half was excellent. It truly was a fantastic game and it's pretty amazing Canberra, Penrith, Newcastle, Melbourne and now North Queensland's first premierships all came down to the final minute of the game.
