Large teams and small teams both have their strengths and weaknesses. Yes being on a TUG or a Delft you might learn things like Bob stated with supply chain management, etc. When I talked to a member of TUG last year they had some interesting ways they manufactured the car. At the same time here at Rutgers we are very small like most others teams. It nice learning to do a lot with little resources and little budget.
Both teams are great like others said it's all what you make of it. Get involved, work on a project, pick up a bunch of new skills and learn to market that to your employer. Being on a team with 100k+ budget and 50+ members or being on a team with 30k budget and 10 members will impress employers, it's just how you market it to them.
