The G29 is also good out of the box. But being an older wheel it has less power and fidelity. The T-gt is more optimized for the game, but that makes sense since the wheel was codeveloped by Polyphony. But as far as I know there is nothing wrong with the CSL either. I have never tried it, but the complaints I have seen are probably caused by the step from compatibility mode to the new supported native mode. Polyphony themselves implemented the Fanatec SDK. People are feeling things they werent used to and probably supposed to be there as intended by Polyphony. But FFB can be highly personal.
