Hasta La Motion!

I have recently been asked to create a small project where various coins are coming out of a tap. I have used Maya rigid body dynamics in the past, but I have recently been very impressed with RealFlow when I used it in a different fluid simulation. I am thinking about giving RealFlow rigid body simulations a go for this project to see what results I get.

My questions are:
a. Has anybody tried both Maya and Realflow for rigid body simulations?
b. If so, were there any advantages or disadvantages to each piece of software in this area?
c. Which one do you prefer using for this type of work?

Any responses would be greatly appreciated. Thank you in advance.
