dig can do everything nslookup can and more. 

OSX doesn't come with nslookup since its depreciated. There's one
case where nslookup makes tech support types think they know what a
problem is when they don't, and they are running up to a limitation
in nslookup (when an authoritative server doesn't have a reverse PTR). 

Its been kind of funny watching some of them defend their position
based on data given out by nslookup that they couldn't interpret correctly.
