Canon SL1 vs. Sony Nex-6 or something else???

There's another factor. "Keepers". I shoot a lot of my kid's basketball games so there is an issue with sports photography that is the number of keepers one ends up with. That is, the ratio between the number of photos taken vs the number of photos that you would actually keep, show, print, opposed to the number of bad shots. I think this is relevant regardless if it's for sports or not and which camera/lens combo will bring you the greater number of keepers. You mention that you've seen a number of great photos with both cameras but how many shots did each camera need to achieve those splendid photos.

You are dead on here. "Keeper Percentage" is a very important factor in the decision process (and oft overlooked). And there's generally very little said about it in reviews.

For instance my own keeper percentage jumped by a whopping 50% when I moved from a 50D to the T4i. Canon has been making great strides in the AF department in the past couple of years. I think the only real Metric regarding keeper percentage that I've seen was the Lensrentals study published recently...

It's an eye-opener.  And my own numbers have borne it out almost exactly.

Even chimping will not always show how bad a shot is until download your photos to your computer and see them on your computer monitor and nothing's worse than coming home with what you think are great shots only to find out they were slightly out of focus. Something you can't always see on the camera's LCD screen.

Actually this has been remedied (since the 50D's LCD), and one can easily determine critical focus when reviewing and zooming-in nowadays.
