It's completely orthogonal, because the SQL involved is just the same.
One of the tests I periodically run is to compare
pg_dump >foo
pg_dump -Fc | pg_restore >bar
and make sure the outputs are word-for-word the same.
What custom or tar format buys you is the flexibility of extracting
different subsets of the dump after-the-fact, using pg_restore's
switches. Of course you can do that with a text editor on a plain
dump, if the dump's not too large for your editor to handle ...
