Both are.

Both are correct.

@ is a shorthand for the current origin, which defaults to the name of the
zone.  Some people recommend using @ so that the file will continue to work
if you rename the zone.  Others recommend putting the zone name in there
explicitly, so you'll catch the error if you mistakenly use a file with the
wrong zone statement.
