Canon has "better glass"? Not so sure about that, but one thing I am 100% certain of: Nikon always has the better sensor in any new d-slr.
Canon EOS 80D vs Nikon D7200 | DxOMark
The 80D is probably the first generation of Canon d-slr to even come close to the new-era Nikon sensors.
I would look at the cameras in the store and see which one you like. Get the camera you can SEE THROUGH the best! Look for a good, clear viewfinder image. Look for a camera that shoots fast (frame rate). The advantage NIkon has is the availbility of older,low-cost,used AF and AF-D autofocus lenses, as well as 60 million pre-AF manual focus lenses which will mount and shoot on the D7200; these older, manual focus Ai- and Ai-S Nikkor lenses are often quite low-cost, and can be a help to the budget shooter.
The Canon advantage is that the EOS lens mount can use adapter-fitted lenses from seven legacy 35mm brands, but that is a kludgy thing for a beginner shooter, using manual focusing on a d-slr, and not having the lens automatically stop down to shooting aperture.
EITHER of these modern, autofocus d-slr cameras are better shooters than most of us grew up using. I would try to get at least ONE, good, fast prime lens for the camera. As I mentioned earlier today in another of your posts, at a high school sports events, you can often get quite close to the action, especially if you are shooting for the newspapper or the yearbook, or the school or district's website. An 85mm f/1.8 lens for $400 or so would be a VERY capable, 127mm f/1.8-equivalent "sports lens" that is plenty long enough for track and field, basketball,volleyball,swim meets, and so on.
If you have only ONE, single prime lens, I would consider $400 spent on the Canon 85mm or Nikon 85/1.8 lens to be money well-spent. If you are very low-budget, look into the autofocus 50mm f/1.8 lens for either camera, and use the 1.6x or 1.5x Field of View factor to make the 50 into a roughly 75mm f/18 equivalent lens using the old-stlye "35mm film format" way of categorizing lenses. In Canon, get ONLY the 50/1.8 STM lens! In Nikon, get the screw-driven AF-D lens for less money and faster AF than the newer ADF-S G lens...the older, cheaper 50mm f/1.,8 Nikkor AF-D lens focuses like lightning!
