Just wondering if anyone can add to a discussion as to why any of the above flight computers are better than the others. If you were to purchase one, which one would you buy and why?

I've been using CN and CNv for five years, and both fully live up to advertizing. Factory support is excellent. The only thing I'd do differently is that I'd NOT have a tunnel mount. It looks snazzy, but it's too far away for these aging eyes. In fact, I think I'd do a pedistal mount for ease of access. From time to time you will want to send it back to the factory for some sort of update, and a pedistal mount will be much easier to remove than digging it out of the bowels of the instrument panel.
