I think the difference is that the England jersey has the red lining. Personally i would have liked to see the collar in red, but its still pretty good.
Really, though, id lie to see any NRL team that doesnt have an iconic design (hoops, the V) to go with something this simple.
It would definitely be an improvement for the Titans or the Storm. Instead of some funky design, make the colour synonymous with the team. (Is i see a plain green jersey, im thinking Raiders)
Edit: i really would like to see the Titans playing in something like this...
(Without those weird wiring lines obviously.)
or in something like this...
