They are not comparable. One is a scanning line display the other is a continuous output beam. There are two big reasons that matters 1. The display behaviour is quite different, on a CRT all but one scan line of pixels is fading to black, on a film this isn't the case 2. Because it is scanning you have two frequencies - the update frequency and the animation frequency. You therefore get beat frequencies and images changing mid scan - aka "tearing". And if you want to know about the difference and whether it matters there is an astronomical amount of proper scientific peer reviewed literature on the subject.
