Joseph - sorry it took me a bit to get back to you. Overall, my opinion on McHugh is mixed to positive. There are times he is very much on target and the other times - well if you listen to McHugh - at those 'other' times he also on target! Benefits are a single site where you can update all the major markets at a glance, update e-wave positions and 'likely' moves to come, follow several proprietary indicators that do have trend/cit value, decent e-wave discussion (including SC-IV patterns/targets), and get a 'feel' for the small versus large patterns in play (including some alternative patterns to consider). You can get all of the above (and frankly far more) via existing chat/trading sites (including here), but during a busy workweek there are times where I just want a quick single end-of the-day read.
Downsides - he (and this is a common problem with many similar sites) rarely admits to 'blowing' a call even when it smacks him in the face, sections of his site (ie: hui/gold) are updated infrequently (I think one section hasn't had a wording change in approx 6 weeks) and have at times been calling for opposite moves (when this occurs - expect that he'll take 'credit' for the right call while the other simply disappears). Despite the criticisms I noted, I find the site above average and of use during my work week. Hope that helps.
Regards
