I would put it in perspective, and just say that at the moment EPL is very good, while HAL is quite OK but not really a world top-ten class, therefore not that many HAL players of today would make it in EPL today.
Australia had a golden generation just about ten years ago, and it has peaked, yet they were all product of the old NSL. Think of Mark Viduka, Harry Kewell, Tim Cahill, Mark Bosnich, Mark Schwarzer (all EPL), or Marco Bresciano (who went from Carlton to Serie A and stayed there for years). Does it mean that NSL was a better quality league than HAL? I personally do not think so, it simply means that they were excellent players, in a long run of local talent developed in Australia that started with Craig Johnston and ended possibly with Mile Jedinak or Eddie Bosnar (in his peak days in the K-League).
All countries had a generational run of sensational, well coached players, combined with good coaching: the Hungarians in the fifties, the Brazilians in the sixties, the Dutch and the Poles in the seventies, the Italians and the Argentinians in the eighties and so on. Local academies, money and the infrastructure have a lot to do with that, as has the level of the competition we compare the generation to (in this case the EPL).
