There are plenty of threads here that will likely give you everything you need to make an informed decision. Start a new thread if you need to or chime in to an existing one for any clarifying questions. Autopilot arguably allows you to do more and it does it better (the trade of being a steeper learning curve and more options to fiddle with in the advanced menus). Litchi seemingly had a greater following as it offered LCMC which is now available in autopilot also. If your a casual user who isn't interested in investing considerable time in doing your own learning and researching I would say litchi will suit you better. Autopilot does take some time to learn.
