Pros of AVR:
Nicer instruction set -- 18F closes the gap somewhat, but AVR is still
better
Good free C compiler (GCC with AVR target)
AVR Butterfly evaluation board -- not just an evaluation tool, but a
handy little thing to build into many small-volume projects
Lower clock rate for a given rate of instruction execution (1 clock per
instruction rather than 4) may mean less EMI, and allows faster devices
without needing FCC approval (exemption for battery powered devices with
clock rate < 1.8MHz)
Company is generous with development kits (frequent seminars where they
give them away)
Cons of AVR:
Tends to be a bit more expensive than PIC for the same functionality
Most MegaAVR parts only come in SMD packages (disadvantage for
prototyping and for small quantity home builders)
Fewer good commercial development tools
Availability of parts in medium quantities (thousands) can be a problem
(evaluation quantities and huge production volumes are not)
