Hello, Deterministic sampling is trivial to implement (but it was rather an issue in the hardware, in the past). It is vulnerable to bias if the metric being measured itself exhibits a period which is rationally related to the sampling interval. Systematic sampling can be easily anticipated, hence is open to susceptible to manipulation. In some cases it can provide better estimates that other sampling methods (pointers to the literature in the document). It is good to have different methods of sampling available for various experiments...
