Nikon's D5300, the latest update to their already class-leading entry/mid-level SLR, not only widens the gap between Nikon and their Canon competitors, it makes the choice to spend a little more money on the Nikon D7100 even harder. Below, I'll briefly explain what has been added to (and what has been taken away from) the D5200 to derive the D5300, but I'll primarily focus on the differences that remain between the D5300 and the D7100.
