I have not done this route, however here is what I do know.

The direct flight to Detroit uses a 764, this aircraft should be fitted with the THIS seat, which isn't to bad.

The food on DL has improved of late and I would say ranks ahead of VS.

For the domestic connection you will be stuck in domestic first class, which while it isn't bad, in reality it's just a bigger seat and a little more legroom.
