To be honest I enjoy playing but I am sort of a one dimensional player. I seldom use air power effectivly and I never seem to get around to building a good navy. Overall the AI is not that hard to beat since it typically plays the attrition game and will only attack if it is at or above parity. I will keep your observations on the bombers in mind for the future.

I generally research up to advanced infantry, tanks and mechanized infantry and that seems to be all I can manage. I am obsessed with maintaining a balanced economy and it is easy to see that the power players (AI) have huge deficits. My biggest problem is producing adequate arms to stay competitive and funding research without falling behind on goods and arms.
