sp_executesql gives you the possibility to use parameterised statements,
EXEC() does not. Parameterised statements have two important advantages:

o No risk for SQL injection.
o Better plan reuse in the plan cache.

For more details on this point, I have an article on my web site that
goes into detail on dynamic SQL, http://www.sommarskog.se/dynamic_sql.html.
