When should I use SQL Query or ORM Search Method to get better performance?
For instance:
Should I use this

query = """
        select distinct license_plate_number from car_car
        where state not in ('cancel', 'sold')
        and license_plate_number = '{}';
        """.format(license_plate_number)
self.env.cr.execute(query)
cars = self.env.cr.dictfetchall()

or this:

cars = self.search([
    ('license_plate_number', '=', self.license_plate_number),
    ('state', 'not in', ('cancel', 'sold'))
])
