I still have a Canon 5D Miii and a lot of lenses for it. (I shot with EOS cameras pre-digital as well.) I do still use the 5D for certain types of shooting--mostly sports and anything that benefits from very wide or very long lenses.

However, assuming I'm taking photos with anything besides my smartphone (which I probably use a greater and greater percentage of the time), it's going to be my Fujifilm mirrorless camera. I think if I were starting over, I'd just go with mirrorless and just forgo the specialized cases that the DSLR and its lenses are better for.
