The latter returns the entire error stack (the clue is in the name). Sometimes the real error you want to identify is some way down the error stack – in which case SQLERRM is no good for you.

If looking for a particular error number in FORMAT_ERROR_STACK you can simply do a:

EXCEPTION WHEN OTHERS THEN IF INSTR(dbms_utility.format_error_stack, ‘ORA-12345′) != 0 THEN … ELSE RAISE; END;
