Any SE version, open matte or letterbox, is soft in comparison to the Cinemax TC; according to bitrate, I’d go with a letterbox version; better solution would be to layer two versions, to eventually squeeze out further details, and a 35mm grain plate would help as well.
I was also curious, your listing says the AXN rip is 23.97 fps, but for me it’s 25. I wonder if I have a poor rip of the movie? The runtime is 2 hrs 43 min for me and it should be 2 hrs 51 min.
