This can be annoying, but you can use hold down the rght mouse button to stretch the units out to 'fit' on the paved streets - it takes getting used to as there is a buffer zone that wasn't there in RTW. Admittedly, I've had some issues with placing cavalry units where I want them, but 99% of the time I can get them there or thereabouts.

One feature I really like in the new sieges is that routing infantry actually run away off the walls rather than standing there waiting to get whacked! This alone has improved my enjoyment of the game.

I also prefer the new system for towers and the town centre, where it seems to be based on the number of soldiers contesting the area as to who is deemed to be in control.
