4k 360 camera comparison: Nikon Keymission 360 vs. Samsung Gear 360 and Kodak SP360 4k Dual Pro Pack

The Nikon Keymission 360 was just officially launched.  With 4k 360 video, it competes head-to-head against the Samsung Gear 360 (reviewed here) and the Kodak SP360 4k Dual Pro Pack (a pair of SP360 4k cameras).  How do the Keymission 360 specifications and video quality compare?

Of course, specs aren’t everything and don’t really tell us the actual image quality.  Check out these sample videos:
