I have used BBB, RPi, and arduino. arduino is closer to real-time if you need that. However, it does only what is programmed in C in a loop fashion. There is a setup() function and loop() function. just about everything is done in the loop. If you need tight integration (real-time) with some piece of hardware, then arduino is the way to go.
BBB and RPi, are linux computers. BBB outclasses the RPi in the number and kind of GPIOs, I2C, etc. RPi has no analog in/outs. BBB does. However, I think the RPi has better HDMI capability. Both the RPi and BBB are linux, so you get the capability to multi-task with separate processes doing something/communicating with each other. You can write your code in almost any language you can imagine. I prefer python, but there are a choice of many others. With arduino you get their version of C - thats it. But with all the greatness of linux, comes the con: Linux is not realtime. It really depends upon what you want to do. But you don't have to settle for just an either/or situation either. You can do dedicated real-time input/output with the arduino, and pass that along to the BBB to decide how to react. So if you can afford it, get both. You won't go wrong.
