The "best digital camera" is the one you can afford. That said unless you're a true enthusiast spending £3-5k on a top end body it's pretty pointless, might as well go for something along with the 70D or d7100/7200.
I brought it to HN from a different angle. Most photographers crop and downsample to help them establish proof of copyright (since they don't have negatives). With 4K screens becoming commonplace, it seems like they're about to lose that arms race.
I don't think it will be an issue for a good while yet and by that time I'm sure new bodies will come out to take advantage of it.
So, yeah, body swap. I guess the war continues :)
