Best practice - use of derived table or use the original table in join?

Imagine I have the following tables in Teradata :

TableA :  Field1|Field2|Field3
TableB :  Field1|Field4|Field5

I am trying to join these two tables

Method 1 :

SEL TableA.Field3, TableB.Field4
FROM TableA 
LEFT JOIN TableB
 ON TableA.Field1 = TableB.Field1

WHERE TableB.Field5<>0

Method 2 :

SEL TableA.Field3, TableB.Field4
FROM TableA 
LEFT JOIN TableB
   ON TableA.Field1 = TableB.Field1
  AND TableB.Field5<>0

Method 3 :

   SEL TableA.Field3, TableB.Field4
    FROM TableA 
    LEFT JOIN (
                SEL Field1 ,Field4
                FROM TableB
                WHERE Field5<>0
              ) DTable
    ON TableA.Field1 = DTable.Field1

Question : I always go for Method 3. But recently my colleague advised it is not the best coding practice as it is using the subquery in join. Is there anything like a coding standard for joins ?
