If you don't need serial connections you can see a benefit from using layer 3 switches with a routing function such as the Cisco 3550 and 3750. They can provide wire speed with smaller ammounts of latency... But it really depends your network architecture and the protocols being used...
RE: what is the advantages of cisco router over cisco switches?
We can configure number of VLan using CISCO switch but for communication between hosts in the different VLan we need router to connect so simple router is a layer 3 device that can send packets to another network switch does not do that.
