Canon eos 200d vs nikon d7500?
Both are 2017 DSLRs with APS-C sensors, and neither has stabilisation in the body, so you'll want stabilised lenses for slow shutter speeds either way. The Canon EOS 200D has the higher resolution at 24.2 megapixels, and it's very small. The Nikon D7500 has a slightly larger sensor at 20.9 megapixels, which matters a little more than the megapixel count if you print big or crop a lot.
Honestly, the choice often comes down to which system you want to join. Canon's EF-S 18-55mm f/3.5-5.6 IS STM is a sensible everyday kit lens for the 200D, and Nikon's AF-P DX 18-55mm f/3.5-5.6G VR does the same job on the D7500. For the sensor size background, see Sensor sizes.
