I definitely agree that Teddy is overrated by the NSW media and to me he is third behind RTS and Turbo. However I have Turbo as the number 1 fullback currently.I'll be in the minority here, but I don't think Tedesco is anywhere near as good as the NSW media make him out to be. I think currently RTS is the best fullback in the game and daylight to second place.
I think RTS matches Teddy in terms of fitness and tackle breaking ability, and then exceeds him easily in terms of offensive output and effectiveness in attack. RTS' ball playing is slightly limited but he is proving effective in what he can do, and he also matches Teddy in terms of support play through the ruck.
Turbo drops behind Teddy and RTS in terms of workload, but this could just be a manly thing as his workload was huge playing for NSW in the outside backs. Turbo supports through the middle and his play against Eels at brookie a couple weeks back should be the textbook of a full back's role in attack.
His ball playing far exceeds Teddy and RTS, his tackle busting and ability to find the line is on par and his defense is on par (RTS probably ahead of all fullbacks for 1 on 1 tackling though)... to me Turbo is on par or better than every other fullback in terms of FB specific requirements and his ball playing far exceeds those closest to him in the discussion... which is why I would have him ahead and ahead pretty comfortably.
