No one likes Lakesbison. It is true that he has been banned at several online forums, and, well, he is one of those rival fans who takes it too far.
As for the comparison of UND and NDSU, I'll start with the rivalry. It is big. It is not as big as it was just 15 years ago due to differences in when NDSU (2004) and UND (2008) went from Division II to Division I FCS and also the current conference situation (UND - Big Sky Conference; NDSU - MVFC).
Here's a wiki link on the rivalry:

As for the teams on-the-field comparison, NDSU - 5 time consecutive FCS national champs - is undoubtedly the team between the two that has had the most recent success. UND played NDSU in a non-conference matchup in 2015 in Fargo (first head-to-head matchup since 2003); NDSU won 34-9. Fortunately, this year's UND team is better (2015: 7-4, 2016: 9-2) and this year's NDSU team doesn't have Carson Wentz (#2 overall 2016 NFL draft pick; current starting QB for Philadelphia Eagles).
Us folks from North Dakota love to talk trash between UND and NDSU (depending on alliance, of course), and depending on how things shake out moving forward, UND and NDSU may both end up in the MVFC soon which would allow the annual rivalry to return.
UND is the flagship university of North Dakota, so in my biased opinion, it is by far the better school and should be on top moving forward.
Go Fighting Hawks!
