I'm not sure, I personally prefer either the Defualt one or the very similar Go launcher. There are normally a choice of two launchers with DroidBOX firmwares, the Android default, and a Metro style, Panel based or faux-3D one (depending on the model and firmware revision. I think the May 2014 X7 firmware has a panel based launcher alternative.
If you want to double check, bring up Settings>Apps>Scroll to the right so you can see the heading ALL>Scroll down until you can click on launcher>Click the Clear Defaults button.
Now when you next press the home button on your remote control, you'll be presented with a choice of DroidBOX Launcher or Launcher I think. Select the first once, and make sure you (for now) click the Just Once button underneath it. This way you can check what the other launcher looks like, without committing to it. Once you're happy which you want to use, select the Always button instead of Just Once.
This process (clearing defaults/Just Once vs Always) applies to all Android applications, when you have more than one that is capable of fulfilling the request you've just made (be it opening a video, bringing up the launcher homescreen or opening a URL).
