Egyptians are Industrious & Religious.....so they can work faster and change governments quickly......However, IMO, the best advantage is that they can build War Chariots (almost as good as Horsemen) early on......for only 20 shields each!...5. Are there "advantageous" civs to be warmongering (ie have you found that one HAS to be a militaristic civ, or would one be successful as e.g. scientific/industrious civ as well?)...
At Regent level, once you've built your core cities (viz. cities that are minimally corrupt), build some barracks (you must produce veterans), make sure you've got a road to the Horse resource, build your War Chariots........and Conquer the World!
