James,
I would use TENT if
1) it's expected to have some anticipation effect (the subject might respond earlier than the real stimulus onset), or
2) there might have some inaccuracies or mistakes in stimulus onset time specifications.
On other hand, if you don't see much effect at the stimulus onset time with TENT or if you don't believe either of the two scenarios happened, it's definitely more preferable to go with TENTzero: a more parsimonious model (occam's razor).
