SQL & PL/SQL

Database: Oracle 10g

--Analytic function (1 table call)

 SELECT a.id
  FROM (SELECT id
              ,row_number() over(PARTITION BY id ORDER BY edate DESC) sub_rank
          FROM tablea
         WHERE edate <= Sysdate) a
 WHERE a.sub_rank = 1;

--Subquery (two table calls)

SELECT p.id
  FROM tablea p
 WHERE p.edate =
       (SELECT MAX(edate)
          FROM tablea sb
         WHERE sb.id = p.id 
        AND sb.edate <= Sysdate);

Both the queries return same results. Basically they get a list of ids.. only the ones that have max edate.
Does it really matter which way i choose except the table scan differences?
