You can create an idea about both devices using the comparative table from the official web page. Since WS-C3560X-24T-S comes with an IP Base Software, it provides you more useful features like: MACsec, protocol-independent multicast (PIM) stub, Enhanced Interior Gateway Routing Protocol (EIGRP) stub and full Open Shortest Path First (OSPF) routing. So, I suggest you use the WS-C3560X-24T-S device.
