The video of the BMW unable to rolled, was the X6. This was due in part to the x6 having a very low center of gravity and hence, they had to induce it by, purposely trying to crash the vehicle (they have a wireless steering controller and a bigger ramp). I could go one more, but thats just too much.

All in all the dynamic suspension isnt a must for most people, as you could purchase other daily driver options (HUD, better seats, better anything that makes your X easier to live with). However if you like taking your X3 on windy roads, or take the highway on-ramp at more than civic like speeds, dynamic is a must.
Dynamic suspension allows more comfortable settings on the suspension setup while allowing it to stiffen up when cornering. It is not as dramatic improvement in handling as active anti roll bar where it does change things when corning by keeping weight where you want it to be.

Anyway, I only suggest dynamic damper if you want more comfort than current suspension setup. Personally, I think the x3 default suspension is just fine considering where I came from.
