What is the difference between ScriptManager.RegisterStartupScript () and ScriptManager.RegisterClientScriptBlock (), how do both do the same?

Question

Hi I am just wondering why some people suggest RegisterStartupScript () to call client side js, while some offer RegisterClientScriptBlock ().

Please let me know what is the difference between them when they perform the same operations for using js operator calls, and which one is preferable if I use only js commands, such as alert, return confirm from codebehind.
