ok so in long peace time it would be better anyway to be a democracy, republic being better only in war time (in which case comm. and monarchy would be better if youre going for a long war)
but if we say : 10% corruption bonus from demo= 10% higher happiness slider to equalize republic's WW,
demo stills better, no? cuz they still get the worker bonus (which may be useful in war to road/railroad behind your forces or simply in front of them to give your military a mobility advantage)
correct me if im wrong?
The problem is, you never know when an AI will backstab you (In fact, sometimes you know they will do it in 5 or less turns, you only wonder who will begin and how many will join againts you, but that's another different thing

)
So, if you feel "safe", that is, none can attack you and cause you noticeable casualties, nor keep troops in your borders for a long time, and you don't plan a conquest war, Democracy is better. However, if you are in an unstable world, where wars declared often, treaties are used as WC paper and so on, I feel safer in Republic. You lose some money and your workers are lazier, but if someone decides to declare war on you, you can stand quite a lot of turns. Demos on the other hand often fall as soon as they see an armed guy stay in their borders for 2 turns!!. To sum up:
Republic: Less productivity, but resistant to war.
Demo: More productivity, but if you get in a war, you are in trouble.
Be aware though that WW acts weirdly, and you can never tell how much it will hurt you

but it is always A LOT worse in demo,
