I bought a '69 when they were new and only sold it after I got married and my new bride begged me to get a car with air conditioning and automatic transmission. I put 120,000 miles on that car and I loved it more than any car I have ever owned.
My current Camaro is a 2013 1LE and it makes me smile like a kid every time I drive it. If you drive the Camaro and the Mustang side by side, which I have done, the handling is far better is the modern Gen5 than the Mustang. Also, the quality of the materials on the interior of my Camaro make the Mustang seem cheap. My son is a dedicated Ford fan and I bought him a Mustang for his first car, so I am not just a Ford hater, I simply like my Camaro & Sierra better than his Mustang and F150.
I like the pics and videos of the Gen6, but I will be in no rush to trade my 1LE with less than 9K miles.
I might change my mind after I see one in person, I know than the interior is an improvement for sure.
