At low RPM's it's hard to tell the difference in torque between the two engines. When you get on it really hard, of course the 135 is faster. The 128 engine is silky-smooth and the power delivery is much more linear over the useable RMP range. Whereas the 135 is more "ballistic" - making it, in my opinion, actually somewhat harder to drive (requires more concentration to drive smoothly) under normal and moderately aggresive street conditions.
The 128i is a great car, but I really don't agree with the statement.
