In the end, the 1080p/60fps is a really big draw.
What do you use to edit?
How much slow-mo do you actually use in your videos?
For all the talk about fps, most video editing programs (like iMovie) don't even take advantage of the extra frames unless you know how to conform the files in advance. I personally stopped doing slow-mos in my edits, as I feel if it's not 1000fps Cineflex it looks cheesy. My 10 cents...
