I have used a 6D for about 3 years and enjoyed it

If you love the original 6D, you'll love this camera

If you love your 6D - you will DIE and go to HEAVEN over the 6D mark ii.

I have loved my Canon 6D for years

I wanted a faster 6D and that's exactly what I got, plus a score of new features like the articulating touch screen and everything else you can read about above
