I think you are talking about two different things.

To get a 128 to go fast compared to other cars requires being in the right gear. A 135 is at least equally fast while being in too tall a gear to produce maximum acceleration. So from the standpoint of not having to pay attention to the gear the 135 is easier.

On the other hand, when you have an abundance of power, applying that power at the wrong time or in the wrong way can get you in trouble. Especially if you have DSC off. From that point of view, the 128 is the easier car to drive fast - because it will not get you in trouble as quickly.

My bimmer is a 128i and I drove a 135i when I took performance center delivery. The DSC was on and the 135i seemed to be totally controllable.
