Should I use a view or a stored procedure?

Which is better view or stored procedure?
A view is essentially a saved SQL statement. Therefore, I would say that in general, a stored procedure will be likely to be faster than a view IF the SQL statement for each is the same, and IF the SQL statement can benefit from optimizations. Otherwise, in general, they would be similar in performance.
Is view stored in database?
A view is a virtual table whose contents are defined by a query. Like a table, a view consists of a set of named columns and rows of data. Unless indexed, a view does not exist as a stored set of data values in a database.
How do I view a stored procedure in SQL?

- Views can hide the complexity of data.
What are the disadvantages of stored procedures?
