I was a happy Canon 70d user before selling the camera to my brother. I think I am correct in saying this was one of the first (Canon) cameras to offer dual pixel AF. The 70D was ideal for me & the purposes I wanted it for; family photos especially grandchildren, holidays & motor racing. It would also have been an excellent camera for nature/landscapes etc, depending on the lenses used. The image quality, overall, was more than sufficient for my needs.
Although I still have Canon kit, I have recently purchased a Panasonic m4/3. Although a smaller sensor, etc, one of its principal advantages (for me) is the significant weight saving.
This is not an easy decision for the OP but what I would strongly reccommend (in addition to the excellent advice in the previous posts) is to try and handle a few cameras to see how they feel in the hand. In my opinion, there is no point in buying a camera body that you're not comfortable holding.
