You are the only person who can answer that question and your answer will only apply to you. The one that seems the most user friendly to me may seem hopelessly obscure to you.
You also need to consider your expectations. If a piece of equipment can only do a few things, it can be very simple to program and operate. The more things it can do, the more choices you need to make when programming. That adds complexity. If you purchase a piece of equipment that is capable of doing a lot more than you're asking it to, then you may come to the conclusion that it is needlessly complex. Conversely, if you purchase a piece of equipment that was designed for simple applications, you may be able to make it work for a more complicated application, but you may not be happy with the things you have to do to make it work.
