They're all equally challenging.

Actually, it depends on the teams there, which team you are, and the game. And, it changes year-to-year as teams change and change events. I would say that we can't predict before the events.

Oh, and team lists aren't final yet. Teams can still sign up for more events, and there are a lot of slots left.

There is a team list for each regional on the FIRST website.
