Both of those threads list many of the things that can improve the out-of-the-box AI (usually referred to as vanilla AI).
And both threads also save everyone from reposting the inevitable solo-vs-mp arguments.

You will find that both sides of that coin tend to no longer play the game in a purely vanilla mode. And its a tendency to compare the heavily modded of one, to the vanilla mode of the other.
