Code Search Tools

There is much discussion going on about code search tools. Predominanty people talk about Google's code search solution. You can access this tool here.

There is also another company called www.koders.com that has silently released a tool for code search. I would say in all aspects the koders' solution is as good as Google's. But I am not sure if koders' one is better! I feel that koders should be working on one such tool for quite sometime now and their tool should be a little better. But thats only "how I feel."

If anyone of you have come across any quantitative/qualitative comparison between these two code search tools, please drop me a word.
