I was involved with HNA Chicago a few years ago. It's a very good league, although on the expensive side. What I liked best is that they split the league up according to ability so it was rare to have one team that was far better than the others in the same tier. It makes for very competitive games.
Now I live in Grand Rapids, MI and HNA doesn't have a league here. I've been playing in a house league at one of the local rinks instead. It cost about half of what HNA did, but it never fails that at least one or two of the teams stock their lineup with ringers (former high school, junior, and minor college players). It gets a little tiresome losing by double digit scores. This season we lost a game 13-3 where their star player scored 8 goals and had 5 assists. I know it's important to play against better competition if you ever hope to improve your own game, but come on. Those kind of games are just painful. If HNA added a league here in Grand Rapids I'd sign up in a minute.
