Industrious civs are my absolute favorites. Egypt, Persia, America, China, France, I almost never stray from this short list of civs unless I've got something special in mind. Being able to build the Pyramids from the very beginning, cleaning pollution in flatlands with 2 workers, it's great.
I've noticed that most games that don't end in an Ancient or Medieval conquest are won (directly in the case of space victories, indirectly for Industrial/modern conquests) because your civ builds infrastructure (road nets, mines, irrigation, rails, buildings) with an enormous worker army while the AI just sort of sits around with a handful of workers and half-developed cities. I'm so used to playing with the Industrious civs that it really bothers me when I'm playing as someone like Russia or Japan or Germany, who I'd really like to get into, but their lack of Industriousness makes me get bored with them sometime in the late ancient era. Among the Industrious civs, I picked Egypt for the poll since Religious is my second-favorite attribute (though it does mean that the Pyramids trigger your Golden Age a bit early, then again, so do War Chariots). A close second would be Persia because of Immortals (which can even win most of the time versus cavalry if you make sure you're attacking and not defending, it's cheap muscle that's good for 5000 years).
