AI economy priorities depends on their personality a lot in starnet (peaceful and sciencey empires will prioritise technology more and fleets much less). Their ascension perks choices will depend on the personalities a little (militarists much more likely to take "quantity trumps quality" perks like the Galactic Force projection or grasp the void and prefer taking interstellar dominion to expand more).

Whether or not you will feel the difference depends on you more than it depends on the mod. If you truly felt the difference between personalities in vanilla then I am quite surprised by it since everyone has exactly the same priorities in vanilla and the main difference between the personalities is their name.
