I think it would ultimately come down to which equipment it operating the route. This is a pretty good order to follow. Not sure exactly where the VS 747 and A340 would fit in, but I would probably slot them in between the VS 787/330 and DL 767.
OP, if you want to mix it up, you could probably try both as the VS codeshare fares often price out pretty close to the all-DL metal fares. Fly DL on the outbound and VS on the return or vice-versa.
