If I could describe the camera in one sentence it would be: More than enough for me, sufficient for most.
I don't personally feel the need to have the newest and most spec'd out camera (nor the money but that's beside the point). The 7D does absolutely everything I need it to, and then some. 19 AF points is very nice, but I don't typically use all of them. Just the center, corners, and sides, the rest is just extra for me. 8 frames per second is really nice for shooting skating and getting the perfect moment. I've used it to make .gifs for my friends, and I found myself throwing out two frames per second as they didn't really add much. So once again, a little extra that I don't honestly need.
Image Quality is sufficient. I don't print often. Most of my photos end up on here, Flickr, and Instagram. Whenever I export from lightroom, I resize the photos down to 8mp (which is still more than enough for my needs). My only gripe about image quality (and honestly the only one about the whole camera) is it has a VERY heavy AA filter. Images can still be sharp depending on the lens, but after using a camera with no AA filter (Ricoh GRii) and even coming from a Canon T3i, it's pretty noticeable. I use Output Sharpener from Google Nik and it comes out great. I am by no means a pixel peeper; I gladly use ISO 12,800 if needed. Throw that sucker in black and white and you're good to go.
The 7dII looks awesome, yes. So does just about every single Canon DSLR released since then (T6 not included), but the 7D does everything I need it to. I don't need 4K video, 16FPS, ISO 400,000, 20+ megapixels, 50+ AF points, etc. I'm really glad I don't have super crazy camera GAS because I would be super broke if I wanted a full frame camera that does 6FPS and 19+ AF points. I don't think most people do need the 5D IV, 7DII, 80D, etc. I guess I've just learned to live with sufficiency because I can't imagine myself spending over a grand on a camera when I have one that does everything I need it to. The only reason I put the "Must Have" so low is that I don't think most people would enjoy the camera near as much as I do.
In conclusion: Canon 7D kicks ass, and I'm gonna run this thing into the ground. Then buy another.
