Why is this still even being debated - is anyone still serious about cottages versus farms? DL's or just coincidental new people who show up only to post this? It's very clear that cottages work very well for a few civs and are weaker for the rest. Though of course a few cottages in certain circumstances (plains, so you don't lose hammers, or just any city with a happy cap) are fine in every empire.
And I would like to point out that Aristocracy itself is really kinda strictly worse than cottages; + 2 commerce that stays forever constant versus the growth you get with the cottages. It's Agrarianism which makes farms so good, giving them an extra +1 food they don't get in regular civ (and Sanitation comes mid-game rather than late). But at any rate what I think is still a far more worthwhile question, the one the OP had, is why everybody seems so crazy about Aristocracy - personally I tend to use a lot of the other government civics a lot. If anyone wants to generate a test game sometime I'm still up for it.
