What is the difference between Get-SCOMMonitoringObject and get-scomclassinstance in Microsoft SCOM?

Question

I have executed both the commands in powershell

1. Get-SCOMMonitoringObject
2. Get-SCOMClassInstance

But I'm getting same results for both the command output.

Is there any significant difference between these two commands?

Environment: SCOM 2012R2 Server

In SCOM 2007, Get-SCOMMonitoringObject is the only command, but it was replaced with Get-SCOMClassInstance command in SCOM 2012. SCOM 2012 doesn't have Get-SCOMMonitoringObject command, but features an alias for it:

Get-Command Get-SCOMMonitoringObject | fl *

ResolvedCommandName : Get-SCOMClassInstance
