I am trying to pick a physics engine for a simple software application. It would be to simulate a rather small number of objects so performance isn’t a huge concern. I am mostly concerned with the accuracy of the motion involved. I would also like the engine to be cross-platform between windows/linux/mac and usable with c++ code. I was looking at Bullet, Newton Game Dynamics, and ODE because they are open source. However, if Havok/PhysX are significantly more accurate I would consider those too.
All I seem to find are opinions on the engines, are there any thorough comparisons between the options? Or does anyone have experience trying the various engines out. Since what I’m trying to do is relatively simple there probably isn’t a huge difference between them, but I’d like to hear what people have to say about the options? Thanks!
There is a nice comparison of ODE and Bullet here:

Hope it can be useful in making a choice.
