The BetterAI seems to do well pursuing other victory types, but this will be included in BtS. Aside from this, I don't see many benefits to BetterAI -- it makes the AI far too passive, and has several bugs. My hope is that, if Blake is working on BtS, that they test it a lot better than BetterAI has been tested...
I think you're being somewhat unfair. There has been a lot of testing by users here but it's quite difficult to make a balanced mod.
There was a major bug earlier where everyone was complaining the AI was far too aggressive. Until the bug was found Blake and Iustus were trying to moderate this aggressiveness. However I suspect that they didn't get a chance to remove all the moderating parts when that major bug was fixed.
