Yeah, that's basically it. The higher the level, the better money-making buildings you can build. The main advantage with level III and IV governments is being able to build higher level "foreign troop" barracks. Government III gives you up to level 4 MIC, and government IV gives you up to level 5 MIC, where you can then recruit generals (in addition to getting the client ruler).

Generally speaking, I'd go for the highest level government possible, except for settlements that you've designated as your recruitment settlement in a particular region, where you want access to the best troops available. Of course, you'll want to use the recruitment viewer to determine which settlements you use for this purpose...
