Go to 15.4(3)M4. That's the golden release at this time. When you navigate to the specific router's IOS download page, on the left hand side, you will see releases that have a star next to them. These are the stable ones that can be upgraded to.

No release does not contain bugs. And if it says there's no bugs then whether the feedback community is not doing its job or no one uses the software.
To answer your question, Sreekanth gave you "the golden release" which means it contains the fewest bugs so far. But you have to know that tomorrow more bugs will be reported and another software release will be more stable. This is the life.

You can review the release notes to see if there are any bugs that could affect your deployment:
