Canon 77D has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Leica X Vario has a
16.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor .
Canon 77D's sensor provides 8MP more than Leica X Vario's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the 77D and X Vario sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 77D and Leica X Vario Cameras
As seen above, Leica X Vario has a 1.1x Larger sensor area than Canon 77D. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.

At Camera Decision, we also look at Dxo Mark sensors when available as we think it is a good indicator of image quality.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon 77D
or the
Leica X Vario ,
including hyperfocal distance.
