Whether to show house property as rented or deemed to be let out?

A salaried person who pays an interest on housing loan of about 3 lacs p.a. and has no other source of income except for salary.
What will be more beneficial, to show the house property as rented property or deemed to be let out?
(because now in both cases, the loss to be set off against any other head is restricted to 2 lacs u/s 71B and further the cf loss can be set off only against house property income in subsequent years)

Thank you!
