We've just made the move from Impero to Senso. I don't think it's as intuitive for the end user as Impero but there are more useful functions.
The few things I don't like are:
1. The PC selection feels clunky. Impero has single click for select all, select power on, select powered off etc. With Senso you need to apply the filter before choosing an operation. You also have to remember to remove the filter afterwards.
For example, if I want to turn off any powered on PC's it takes 4 clicks with Impero. The same procedure with Senso is 6.
2. I prefer Impero's Operate dropdown list as it's quick. Senso has separated the End Session (Log out, Shutdown, Restart), Power On and Remote Logon.
3. If you have control of a PC (or are viewing in full screen) you can't use the console for anything else. It needs a pop out window option. I like to be able to control/view more than 1 PC at a time, which Impero allows.
However, hopefully these things may come as development is always continuing which is one of the reasons we made the switch. Impero hasn't changed in a very long time and is less and less reliable. The keyword logging is a great feature as is the word cloud (though it needs some work to stop detecting part words!). We'll be reviewing again in a year but I'm hopeful this will be a good change.
Also, support is fantastic! We have been working closely with Alex and the issues we had have pretty much been sorted out and quickly.
