Some of the ideology lines are SO MUCH BETTER than the others.
For pragmatism the overpowered line is the second one, the Constructor/Starbase line. The "no one can declare war on you for 50 turns" ideology is pretty good, but the rest of the line is pretty useless.
For Benevolence (larger maps): the first and last lines (Colonization and Research lines) are MUCH MORE USEFUL than the other two.
For Malevolence: The first two lines (Invasion and Production) is SIGNIFICANTLY better than the other two.
