both are useful

the block hash proves knowledge of some information that couldn't have been available before (same as using a newspaper headline, for example), so it puts a >= bound on the timestamp

OTS stamping can be used to prove that information already existed at a certain time (by putting it in a merkle tree that will be published in a block), so puts a <= bound on the timestamp

together these can "box in" the timestamp of the event
