I agree with you regarding the need for special computers. Without SDS, diagnosing M104 issues would be tough. With SDS, it's very easy. The reason I prefer the M104 though, is the performance. The combination of adjustable camshaft timing and the resonance intake manifold, along with four-valve technology, make these things
fun to drive.
