IMO Garmin is way the best solution.
My personal opinion is different. Not in the least because COMAND is a lot more than just the sat-nav. It offers integration that no after-market system can provide and there is less risk of someone smashing your windows to nick it than with portable aftermarket systems (and you don't need the actual device to be in the car for that to happen, just the tell-tale markers on the windscreen of where the suction cups were attached is enough.
It's one of those things where there is not a single right answer, it depends on what specific functions and other considerations are important to people.
