Photons to Photos did an independent comparison of the latest Fujifilm sensors and the data is a little surprising. It seems the Fujifilm X-T2 has a dynamic range advantage over the Fujifilm X-T20, X100F, and X-Pro2, as the ISO rises. Yet, The Fujifilm X-Pro2 seems to have an insignificant noise advantage. The dynamic range differences are likely due to the varying thermal designs of the cameras. You can manipulate the dynamic range chart here and the read noise versus ISO chart here.
