I'm a big fan of Nikon DX kit, I currently have a 7100 and I love it.
I have occasionally thought about going to full frame, but I've realised that, like everything in life, it's not the equipment that's the limiting factor.
Plus of course the positively eye-watering cost, a Nikon D850 body is getting on for £4k. Mind you, the Df is a lovely thing...
