You can use plastic or metal, it's mostly a matter of personal preference and budget.  Kitchen sink drains are typically 1 1/2" while bath sinks are 1 1/4".

Hi Wahdee!

As Adam has indicated, the kitchen tailpiece is typically 1 1/2-inch and bath tailpiece is typically 1 1/4-inch.

The downward angle of the inlet helps water move down the drain ... preventing the dishwasher from backwashing into the sink.

Hello Wahdee.

Yes, your kitchen tailpiece and trap will be 1 1/2" size.

The choice of metal or plastic really comes down to whether the pipes will be exposed.  If you have a sink where you can see the drain pipes then metal will look much nicer.  If the pipes are behind doors, (typical), then plastic is both cheaper and will not corrode over the years like the metal ones do.
