Below is a list. I have compiled it in December 2008. Obviously, it's not a complete list, and it's merely a single opinion.

Pros and Cons of ARMs (compared to PIC18)

Pro:
• Ample resources (ROM, RAM)
• Faster program execution.
• More sophisticated interrupt architecture
• Exceptions
• C++ compilers, which might speed-up development and facilitate code reuse
• JTAG
• Many silicon vendors
• Many flavors

Con:
• Smaller mind share
• Lack of small device (the smallest one is 48-QFP)
• Larger amount of necessary external hardware

Hi,

Comparing a 32 bits ARM with an 8 bits PIC18 is like comparing a bicycle with a truck...

A fair comparison is comparing an ARM with a PIC32.

Actually there is a benchmark done by an independant source called coremark.
Just select NXP (Cortex M3 core) & Microchip :
http://www.coremark.org/benchmark/index.php?pg=benchmark

You'll see that the result is that the 80MHz PIC32 scores higher than the 100MHz NXP device...

If you want to get started : http://www.microchip.com/PIC32

regards
