AVR microcontrollers have a RISC core running single cycle instructions 
(instruction cycle 62 ns@16 MHz) and
a well defined I/O structure that limits the need for external 
components. Internal oscillators , timers, UART, SPI, pull-up
resistors, pulse width modulation, ADC, analog comparator, and watch dog 
timer are some of the features 
AVR instructions are tuned to decrease the size of the program whether 
the code is written in C or Assembly. With on-chip
in-system programmable Flash and EEPROM.
I also belive that this argument was about memory expanders, not 
iR-linking.  and the AVR is a better choice than the pic.
