Comparison between PIC16 and Atmel ATmega

[aruna1]

Hi
This a question from one of my exam papers.I searched all over internet but couldn't find any article or information source comparing atmel vs PIC in following manner.
all i could find was threads talking about which is better.none of them discussed the matter with respective to following points.
so can some one help me here?
thank you

Homework Statement

I'm not sure how to answer the reliability question, but the others can be answered by reading their datasheets/databooks.

ya i read them but couldn't figure out different of
1.microcontrolller core
2.ALU capabilities

What did you get for the rest of the answers?

well for architecture they are similar-harvard,RISC architecture
for instruction set PIC has 35 and atmel has 131
for reliability i was thinking about features like WDT and BOR
