Explicit joins allow you to order the joins any way you want. When join
conditions are in the WHERE clause, you don't have any control over the
order in which the tables are joined.
Additionally, when you do an explicit join, you can perform other types of
joins, such as an inner join, outer join, etc.
Personally I prefer doing explicit joins because it makes my SQL more
readable to me; all the glue that joins the tables together is in the FROM,
and the WHERE clause just limits the rows that I want returned.
