Use one only, if you dont like the mini BAI tweak i do, and wanted only use CAI part only just use the one with CAI, i highly reccomend play with normal version, to ensure more high quality troop in later turn.
The mod dont alter CAI unit recruitment departement, but i only encourage CAI to produce that, by faster the reseach and give them cheaper recruit and upkeep unit cost, so less economic burden, enable them to build better and recruit more high quality troop.
Easy edition you play will only give AI 10 % bonus more cheaper to recruit and maintain army only. There is no crazy income cheat money for AI in any version.By playing the Easy Edition mostly your are on par with CAI on term recruit army. Hope its help
