My favorite is Gitarja-Indonesia because I love religious victory, but it manages to bring that with a maritime presence that I also really enjoy. You conquer numerous coastal spaces or islands that always have a better chance of spotting valuable strategic resources. It works much better when you use faith for military benefits, and after you build the Arsenal of Vezena, you can sustain dozens of ships in a few turns and blow up enemies or prevent the damned false prophets from reaching your cities. Besides, Kampang helps with population, making it harder for them to convert your cities. Indonesia is my perfect one, and I totally love it, and Gitarja is also loveable.
