Which of these are more critical to building a Winning Team/ Venture?

Comforting to know that majority of the last poll participants believe Team is the most critical component to build a successful business. Thankfully, we at VenEx (GetVenEx.com) are working on this most critical one. But, despite the years of diverse experience, my co-founder Avi & I often wonder what aspect is the most important one for building a Winning Team/ Venture. Would love to know your views.
