Canon, Nikon, Sony, Fuji, Panasonic, etc, there is lots of choice. Remember, though, it is not just about the body but also the lenses. Once you have made your choice you may find it difficult to change to another manufacturer in the future as you wil probably have body and lenses to change. OK you can get adapters but you may not want to do that. Also you may get stuck with an old lens system. As new mirrorless cameras are introduced new lens systems are also coming in. The Canon EF system, thieir mainstay for many years is one such lens system.
I have only changed manufacturer once. Choose wisely or it can be expensive.
