As the title says, what are some of your favourite non-unique government forms? Everyone knows the Tsardom and Mughal Diwan as being very powerful government forms that add a lot of oomph to their respective tags, but what about the not-so-special government forms shared amongst multiple tags?
Steppe Horde is an obvious choice, so I would like to nominate Iqta and the Indian Sultanate. The taxation policies are pretty good IMO - Lenient Taxation is often used for opening alliances, Land Acquisition is minor but still an extra 5% CCR to stack with other sources, and Efficient Tax Farming is really good early game, when taxes reign supreme, and you can get a lot of ducats from subjects. Going colonial as Andalusia lets you cash out thousands of ducats from this interaction.
