From a technical perspective the Xymon client checks are executed by the client server, that is to say the client computer decides when it is going to run each of the tests, it runs them and sends the data back to the Xymon server.
With Nagios it is the server that decides, it contacts the client and gets it to execute a remote program via NRPE then retrieves the result. If you have a lot of clients then you are going to have a huge number of processes on the Nagios server executing remote programs on all of the clients. This is both a benefit and a problem for Nagios. +: All the configs are on the server. -: These config files can get very complicated.
