Difference between v_R_System and v_GS_Computer_System views

While doing queries, it is confusing which view to use-v_R_System or  v_GS_Computer_System

v_R_System View is from discovery - information populated by discovery info.

v_GS_Computer_System is from hardware inventory. Information populated by received inventory of clients.

Thus v_GS_Computer_System is from WMI, v_R_System depends on the discovery.
