Right now I only use your 8 Ages of Pace and Seven05's Larger Worlds and Detailed Worlds mod.
Oh and personal preference for if you were to update 8 Ages of Pace: I'd prefer being able to have just slower techs and civics without having faster movement on roads. But that's a personal preference and I also know that you can't make a mod specifically for me because then I should just do it myself.
As for AI+, I would actually argue that it is better not to use it. It has not been updated for the last two patches, and I remember Siesta Guru himself saying, around the last patch where he updated the mod, that because of how the mod worked it also broke some things that were actually fixed with the patch in the base game, and I know that at least the Spring Patch had substantial improvement to base game AI, and they did stuff for the AI in the last patch as well, though I haven't played enough to know anything for sure yet. In other words, chances are that the AI is actually worse now if you use AI+.
