Is there any performance difference between using a Temp table and using a Table variable?

Yes.
A variable takes less resources to create but gives less optimisation options less indexing possibilities and you also can't detect it's existence or size from another spid.
So table variables are usually used for small tables and temp tables for large ones.

Cursors are useful if you don't know sql.
DTS can be used in a similar way.
