I prefer to have an army for the region able to come and relieve a siege. Plus it means that you get a proper field battle, rather than yet another tedious siege to play out.It doesn't seem to have been answered previously, but better quality archers are a good idea for cities you expect to be attacked. Better ranges mean more shooting time before those siege towers reach the wall. A cavalry dash can hold up the siege machinery too, which can help buy time for the archers to do their job.
