I just finished an abundant all immense game on the latest build and can say that on suicidal at least the AI had no problems colonizing or building PI. Not that there was any thought given to what PI's it did happen to build, but it built them.
On Maso, the AI is seriously outgunned.
That being said, IMHO i won't get the use out of TA that i do with DA, personal preference, but i would still reccomend you buy it. It's far more receptive to modding.
