T-stops do not consider the micro lens structure of the sensor, it only says something about the lens. You hardly find T-stop info anyway....
I use a 55mm f1.2 lens regularly, not for the low light extra-ability but for the sake of it.
By the way, you can test the microlens light loss extra amplification with your f1.4 50mm. When the camera "knows" it is at f1.4, it gives a bit different exposure than when you unmount the lens just enough to not let the electrical contacts make contact. The bigger the aperture, the bigger the difference between exposure times or brightness results.
