Syslog is strictly a logging tool. The router will send syslog messages to your server as and when they occur.
On the other hand, SNMP is more of a monitoring tool that also gives you asynchronous notification of events (in the form of traps). In that second respect, SNMP and syslog are similar. However, SNMP gives you the ability to actively poll the routers, which you do not get with syslog.
One advantage of syslog is that you can maintain long-running history files of your logs (although some SNMP managers will let you store history files for your traps).
In networks I use, we use both of them and they provide complementary functions: SNMP gives us polling info and traps which we need to act on urgently and syslog stores data for us that we sometimes need to determine issues that may have occurred some time ago.
