Meh. Never had a bad experience at ANZ personally. Results aside of course. My members seats are awesome, I always find free parking, it's dead easy to get in and out of the place and although the food and drinks cost an arm and a leg, you never have to que so you don't miss much of the game.
Go to somewhere like Leichardt or Brookvale and its a completely different story. Sure you're close to the action but everything else that goes into game day becomes 50x harder. Parking, getting food, getting in and out, all a pain in the arse.
I reckon
1. ANZ
2. Parra Stadium
3. SFS
and then the rest in terms of grounds to watch Footy in Sydney.
