Actually there's a guy at the Civfanatics forums named The Me In Team who autos everything. He autos workers and uses the governor feature. He plays Emperor level I believe. His argument is that in the early game micro workers, but as the game gets along he autos them, and as long as you use it with the governor feature (i.e. emphasize x), then they'll work terrain how you want it. Also he's one of the fastest players around, completing the average game in about 2 to 3 hours.
Also, Civ 4 and EB are about the same for me. It really depends on what I want to do and how I'm feeling. They're two of the only games I actually play nowadays, so there's plenty of room for both of them.
