If you are doing a delete of a set of records, as apposed to a delete of ALL records, then the table is scanned to locate the records to be deleted. The delete action also affects any indexes on the table. Insert also affects the indexes but is less costly.

Update only affects the indexes if the indexed fields are updated.

You can do both in management Studio with the execution plan and costs turned on and compare your specific process.
