Maybe I am misreading you but I don't think more complex or sophisticated is necessarily the "better" choice for people even if everything else is equal.
This is particularly true of the new avionics packages. The issue is rarely one of knowing what to do when all is well but rather what to do when something didn't sequence as was expected or when things come fast from ATC. Just compare Perspective (basically G1000) vs. Avidyne's R9. I would argue that R9 is much better for the 50 to 100 hour per year pilot even though Perspective is as capable if not more so. R9 lacks deep menus and has a more fixed interface (buttons with fixed labels).
Call me a wimp but if FADEC's weight, cost and reliability issues get solved I would love to have it. I think getting rid of the boost pump and mixture control would be great.
All that said, I would love to own a Cub but that's for a different mission. The Cirrus is a trip plane.
