Replacing Bay, Bow window?

I want the best possible window that has the best insulation. Would you say vinyl or wood? I want the inside white. The outside is going to be white, I have white aluminum siding. This is going to be a large living room window. Any ideas of what the specs. of the window should be? Like double or triple pane? Again the insurance is paying for a good portion of it I just want the best out there. Thanks. I live in n/w Indiana and the window is on the south wall.
