There is a noticeable difference. Very little turbo lag to speak of. In addition, the 123D pulls well in almost every gear. With the 320D (163 bhp), the torque was lacking when engaged in 5th and 6th gear.
You mentioned the interior quality; I think the materials used falls slightly short of the 3 series but I much prefer the design of the dashboard on the 1er. Horses for courses really.
