I'd say it depends on what you're shooting. I have a d5600 and Z5.

The Z5 is better for baby pictures.

The d5600 is still better for hiking and travel pictures.

The Z5 is better under low-light and dynamic subject conditions. Particularly because the digital viewfinder is clearer in the dark, the eye/face autofocus and low light autofocus performance is much better (much fewer missed shots), the Z5 has sensor-shift stabilization, and there is no mirror slap affecting lower shutter speeds. For landscapes where there is lots of light, a lightweight and battery conservative d5600 still does the job excellently.
