Make Controller is the fastest and most expandable. On the downside it costs 2 X Wiring and 5 X Arduino.
Making things' support forum has 250 threads; Arudino has 2,500 threads and over 11K responses.
On the other hand, the Make Controller would be good if you need a lot of IO, multiple serial etc. Have a look at wiring too.
The way to choose a controller is to block diagram the circuit and then see what the hardware requirements are, then the processing requirements, then the power requirements, and then have a look at the things like price, support, availability etc, as in the first paragraph above. A big consideration might be something like: do you want to learn assembler or C for a particular controller? How much time do you have to spend on it?
Often one feature or another will often make the controller choice obvious: say you need four serial ports or something like that. Arduino is great for flexibility, cost and community. If you need heavy processing, then it's not what you want. And so on....
