EHL is probably the best Tier III league in the country. Obviously every league has the haves and have-nots, but the EHL is considerably better than the NA3HL. As for comparing it to the OHL, the O usually has 5-10 players picked in the first round of the NHL Draft let alone in the other rounds. If there ever has been Eshow players drafted, then they don't number more than a handful. The USHL in most hockey minds is at least an equal of the OHL in both level of play and NHL Draft picks so the same goes for them.
EHL is a solid league and leads the country in Division III commits. They expanded this year and some of the newer teams are horrid, but the league parity remains very good. But it's a Tier III league and so it's not fair to compare it to anything higher than it, in Canada or the US.
