It really depends on what you want. Usually 60 fps is beneficial if you're uploading to a site that supports it, or you want people to "appear" to be watching the game in it's native framerate.
For the most part, almost all of us are used to seeing 30 fps videos, so it wouldn't really be an issue sticking to 30. However, 60 fps just, for the most part, is really not quite what's it hyped up to be unless you have really high quality standards (unless 60fps becomes the new norm, in which case the future will tell)
