TOD has the campaign feature whereas VN doesn't. Also, there is the "House to House" custom scenario package for TOD that adds a lot of the SB features that came later to TOD. In the end, if you are interested in the Vietnam war both would be a good choice. There are probably stats some where on this site that will help you determine which one gets more play.

RE: Vietnam or Tour of Duty
There are a number of custom scenarios for both out there. The House to House scenarios that Mike Cox did for the TOD update are fantastic. Either way you go, you'll have quite a range of scenarios to choose from.
