re: Maybe discussed already but who has the bigger advantage?

Wisconsin players will have an advantage having repped against this defensive style for a few years now, so the players can recognize some things easier.
LSU coaches will have better player scouting reports from Aranda, but Chryst has been calling offenses for so long at Wisconsin, Pitt, and now Wisconsin there might not be much Aranda could bring over schematic-wise that LSU didn't know.

The big plus in LSU's favor is that any Tiger corner could probably have started (on a pure talent basis) over anybody Wisconsin's had at that spot in the last 3 years. The ability to use corners as weapons, comfortably relying on single coverage against a mediocre receiving corp and possibly blitzing is the big key on that side of the ball. If LSU can sit 8 in the box regularly, Wisconsin won't move the ball.
