Depends on what you want to do and how you want to do it.

The RTek2.1, is perfect for a little more tunability than a piggy back system, but doesn't have nearly as many inputs/outputs as after market ecu's. Basically on the S4 N/A you get one aux input, and one aux output (with the behavior of an RPM switch). I personally went this route as it provides more detail in tuning than an MS, but doesn't have the nice features that the MS has for the equal price.

Future upgrades are possible with the RTek (see the AFM delete, and other possibilities). It also has the benefit of using Palm devices as multigauges and datalogging. Compare that with other piggy back systems and ECU's you'll be hard pressed to find it.
