I think you do well to hesitate before using TempData. TempData is stored in the session and this may have implications for you if:

1. You don't use sessions on your site right now
2. You have a system that needs to scale to high throughput, i.e. you'd prefer to avoid session state altogether
3. You don't want to use cookies (I don't know how well MVC supports cookieless sessions right now)

If your site needs to have high availability, then there are additional considerations around applying session state but these are all solvable problems.
