I tend to prefer tall cities, but i've just realised the drawback to this - garrison units pay no maintenance, but you can only garrison one unit per city, and i can only afford the maintenance on a limited number of non-garrison units before my gold income goes negative.
So, let's say I have 1 population 20 city, with 1 garrison and 3 extras. The AI sees i've only got 4 units in my army and thinks i'm an easy victim. If i had 5 cities at size 4, i could have 5 garrisons plus my 3 extra units, and the AI will see an 8 unit army (twice as big).
In reality, those garrisons have to stay where they are and if any city comes under attack, i've only got the same number of defenders, and 4 units is plenty to defend one city with, especially when it's big , high HP one.
But I keep getting nuisance DoWs, usually right about the time I'm finishing my National college or whatever, have grown my main city to 15 or so and am working all the riverside/special tiles within 3 hexes, and was just about to start a second one.
Suddenly my neighbour DoWs and though they end up getting their clocks cleaned, i loose production/growth from having tiles occupied / pillaged /workers in hiding and civs that didn't join this little war get ahead. Worse, the fact that you're already at war lowers your "estimated strength" in the eyes of the AI, so you get more and more nations joining in the dogpile...
