Is it worth buying the Canon T5i for $599?

I've been interested in purchasing my first DSLR camera. I didn't want to start off with an entry-level camera which was why I chose this camera, also because it's a good deal. It's usually $929 in Canada, the features and image quality on this thing look pretty good. The only thing I don't like about it is that it's 18 megapixels and doesn't include wifi or bluetooth. I was also considering the Nikon D5300 which is 24 megapixels and includes wifi and bluetooth, but it's an extra $200. Other cameras I've considered were the Nikon D3400, D5600 and the Canon T7i. Professional photographers please help, thanks!
