Well, a thread in flames..... 
I do not pretend to have the definite anwser for the " Who pwns who? " in terms of Civ III vs Civ IV . Civ III definitely has a more stable core, supports more cities and bigger maps in the same computer, has more mods and unitpacks.... Civ IV IMHO has a better core mechanic ( in spite of some big issues with loose strings, like the vassal system, espionage,.... ) , it looks better ( in spite of some very beutiful Civ III units... we're comparing core versions, not mods or unofficial x-packs ) and got rid of some of the annoying civ III features ( like corruption ( IMHO, it was stupidly implemented ) and polution ( idem ) ). So in the vis-a-vis, I really think that is a matter of taste....
But there is a argument posted here against Civ IV that I agree: the 3D engine. I understand that the current graphical cards handle better 3D than 2D, but I simply don't understand why do we have a fully 3d graphical enviroment that is completely eyecandy, not fullfiling any kind of pratical use in game. If we had a SMAC type enviroment ( with diferent heights and depths, and sattelites ) 3D would be awesome and would fill the propose of the game, but that is not the case of Civ IV ( by design choice: the code allows its use, like it was discussed in the SMAC Mod thread ). That makes a very heavy-processing game for the actual computing needs of the core mechanics ( read "fluff" )
For finishing, I have SMAC ( not the X-pak... didn't liked it ), CivIII Conquests and Civ IV BtS in my computer. I play them all, but BtS has a big advantage over the other two. I play SMAC 1/2 times per month ( love the unit workshop, the deformable terrain, the terraforming ,and the awesome diplo system ( far better than any one of the Civ series ones IMHO ) ) and Civ III is pratically idle since last year ( never were a big fan of it: IMHO SMAC had a better core..... )
