define easy.

If you don't want to build a controller in a box, then both Falcon and HC sell "ready to run" controllers in an enclosure all wired up ready to go.
If you're happy to build your own enclosure, then falcon or kulp boards are the way to go. The Falcon used to be the most popular by far, but recently Kulp boards have also become quite popular.
IMHO they're all about as 'user friendly' as each other, however there's much greater support from xLights and the lighting DIY community for Falcon boards and more recently Kulp.
To confuse a new person even further

all manufacturers sell multiple types of controller boards, some are better suited for spread out displays.
