Canon DSLRs are better than Nikon DSLRs, the difference is that Canon DSLRs have a larger lens base, and the Canon 800D is recommended.
Recommendation:The Canon 800D features a 24.2 megapixel APS-C CMOS sensor, which you can also find in Canon's more advanced EOS 80D (￡840 body). While the 750D / 760D also has a 24.2 megapixel sensor, neither of them feature Canon's Dual Pixel AF technology.
While the effective resolution is exactly the same as the 800D's sensor, it represents a considerable improvement. High-resolution power can be utilized to finely render subject details such as leaves in a forest, street roof tiles, and people's hair. By appropriately allocating pixels within the effective space, high image quality and low noise are realized.
Similarly, the 800D utilizes Canon's Digic 7 processor (later replaced by the Digic 8). Canon claims that the Digic 7 is capable of processing data at speeds up to 14 times faster than its predecessor, which not only allows the 800D to deliver a higher 6fps maximum burst speed (compared to 5fps on the 750D / 760D), but also fires a much higher number of consecutive images during continuous shooting.
The new sensor and processor pairing also allows the 800D to offer a higher ISO 25,600 maximum raw sensitivity setting, as well as an ISO 51,200 equivalent setting in Extended Mode. Supporting touch control, the touch LCD panel allows for intuitive smartphone-like operation. In comparison, the 750D / 760D both offer a maximum native sensitivity setting of ISO 12,800, which is equivalent to ISO 25,600 in extended mode.
