The stock T300RS pedals are worse. Definitely worse than G27. The plastic base is not rigid enough and the brake pedal isn't firm enough to threshold brake comfortably (although it is better than the DFGT pedals). Accelerator is acceptable. If you still have your G27 pedals, Thrustmaster and Ricmotech both sell cheap converters to run your G27 pedals from the T300 base (works on consoles and PC). If not, then the T3PA pedals are a highly recommended purchase, for example in the T300 Alcantara package (T300 base, 599evo alcantara rim, T3PA pedals).
