Imho the 60 FPS just looks too smooth. I loses all that dreamy and cinematic feel.

Cool for editing but as a base setting it’s too weird (imho).

4K at 60 FPS gives you a lot of flexibility for editing. You can crop in, slow down and still maintain 1080p at 30 FPS.

If you don’t do video editing etc. I would recommend to save the space and stick with 1080p at 30 FPS.
