sadly under the current mechanics a specialist economy wins hands down vs a cottage econ. let me explain how and why i come up with this.
assume a city cap pop of 8 workable tiles. plan on any extra pop to go to specialists. you really have to have this in your head at the start. now, in the above example someone stated they skipped agriculture. You NEED farms for a specialist econ , agriculture is a must.
so , if we look at the tech path of agriculture -> mysticism (going with that free tech in the way) [fyi if agriculture is your free tech your kinda better off ] . with mysticism you get to use 2 specialists both of which come in very handy. if you get a sage you can make and academy or join for beakers , if you get a priest you can get a religious wonder or join for hammers and gold. both of these option are very useful.
How do you get the gold to pay for city maintenance? I once tried to bypass Education for a long time and go for Mysticism. Even with two specialists per city, I couldn't support my expanding empire, and was running into a deficit even with 0% science spending. I also had nothing useful to build after the first couple buildings - building more settlers or conquering cities would be suicide.
