It depends on what sort of front end you are looking for.
The main ones are HyperSpin, LaunchBox, AttractMode, HyperPie PC and a few others that you should look into.
How much HDD space do you have?
What kind of look are you going for?
What systems do you want to display?
Ask yourself all these questions.
