It's very simple to use, it has all you need in one platform (CPU/Memory Monitoring). And I think that with other applications there are more functions added but at this moment everything what we have can be used for our purpose so far no complaints here! We're using now mainly memory usage by user level which helps us identify where users spend most of their time doing workstation tasks or when they do something else than working etc., This also helped me find out if some people waste too much
