The best route is actually determined by the longest prefix match

Priority does not affect route selection; it is only for the DR election
process in OSPF.
Cost does affect route selection. OSPF determines the best route to a
destination based upon the metric called cost. By default cost is calculated
using the formula :
Cost = 10exp8/ bandwidth of the interface ( i think so :) )
You need to set the correct bandwidth for serial links using the bandwidth
command. Make sure you understand that the bandwidth command is just an
informational command that tells the different routing protocols about the
actual bandwidth of an interface. This command has nothing to do with the
data transmission rate.
