I am of the opposite opinion. I drove a 540i Sport with multiple Dinan upgrades. Incredible car, loved it. Then I bought a 550i Sport (E60) and I love it even more. Took a couple days to get used to the different "feel" of the car, but there has been no looking back. Absolutely fantastic car.

I still am sorry for ever trading that car for an E61.
Next up, I'm going to buy either an F10 550 or an F13 650. Hence my hanging around these forum.
