D7200 or 100?

[NvidiaDan]

Hey guys, looking at getting one of these cameras as an upgrade from my d90.

For pretty much the same price (possibly less) than the 7200 body I could get the 7100 with a 35mm F1.8 lens with £120 cashback or free battery grip.

Is the 7200 worth the extra?

I shoot mainly aircraft and aviation which can involve some burst shooting, but I find myself shooting in large jpeg instead of raw nowadays anyway due to storage requirements. What's the buffer like on the 7100 for large jpeg?
