I have most of the options and am happy I got them, though that is probably just my reaction to owning cars that always had few or not options. If I get another BMW, I will probably again want the tech, cold weather, and premium packages.
If I were to have changed an option it may have been getting a RWD 6MT instead of the xdrive and 8AT. I'm still very happy with my powertrain and I believe the forum has given this topic a thorough discussion already
