It is a matter of personal shooting style for sure (the whole buffer issue). People took stunning wildlife, bird and sports photos when today's buffers were but a figment of someone's imagination.
The trade-off of the D7100 is less buffer, but you do gain ISO performance, dynamic range, tone/color, metering, autofocus, etc, etc.
Is that worth adjusting your shooting style if you are used to a large buffer - people will differ on that.
I had to adjust my shooting style when I moved from DX to FX and again when I moved from the D700 to D800 (although that one was more minor). I think it has made me better as a photographer, but at the time of the changes I was vexed.
