These two cameras are so dis-similar that you are not comparing cameras, you are comparing concepts.
Here is a comparison of specifications:

You have to ask youself, what do I want my camera to do for me?

I want to buy any one of the two. If cost is not the comparison factor which one is better. Olympus C740 ofcouse has a great 10X optical zoom. But Coolpix has good low light snapshots. Please help me out
