I'd typically say that you should have drive team members from multiple sub teams, this way they can deal with/fix any problems a robot may have on the field since they'll be the only ones who can fix it at that current time. That being said there's also many other factors such as talent, commitment, time put into the team, etc. But it's really up to you to decide what matters the most to you.
