Yes, I agree. I especially like that there is only one return statement. In contrast, using multiple return statements violates the principle of DRY.

Conway recommends formatting tabular ternaries with the colon at the front, for example: 

             # When their name is...                Address them as...
my $salute = $name eq $EMPTY_STR                  ? 'Customer'
           : $name =~ m/(.*), \s+ Ph[.]?D \z /xms ? "Dr $1"
           :                                        $name
           ;

because, if you squint, it looks like a lookup table, thus converting the notoriously impenetrable ternary syntax into a familiar and easy to understand lookup table.

Update: Fixed typo in Conway's example my $salute statement above (removed extra ?). Thanks AnomalousMonk.
