3 quick points:

1) The OP didn't specify the application.

2) The OP was using a 16F84 which is more costly than any other 18 pin PIC.

3) Even if you go smaller/cheaper in production, it's always a good idea to
   design to the part with all the resources, then figure out why actual part
   meets the final requirements.
