It's not more lifelike, it's more dream like, what movies should be. You can do a lot more with exposure and lighting with 24 fps. You can suggest a lot more with 24 fps. You can hide a lot less with 48 fps or 60 fps. Games choose to hide things in the dark to suggest more than there is. That works for movies as well, however a lower frame rate is just as effective.
Some of those effects sometimes help games look more realistic (of course, this depends on the genre/scenario) and most of them do not hide the frame rate. Motion blur is the only active feature that truly masks objects that are moving, and even then, it is more effective at lower frame rates. Turning many of those features off, in my experience, doesn't leave a feeling of a sterile production, but then, that again depends on a number of external factors.
The variation of preference for lower vs higher frame rates is simply preferential.
