In my opinion, there are two different definitions of toughest when it comes to a regional. Level of difficulty with teams, and level of difficulty in regards to winning the competition.

Teams: A tough regional in this case is one with a lot of powerhouse teams, Midwest in this case. It is not necessarily difficult to win in the regional, as there is a lot of variability when it comes to elimination matches, considering a good sum of the alliance will have at least one alliance.

Competition: A tough regional to win is a regional with about 2-3 powerhouse teams, assuming your team is average. It will be very likely that one of the powerhouses will become #1 seed, and its also very likely that that team will choose the other powerhouse team. I am not saying that this will happen every time, but it is a likely possibility.
