Both Sony A6300 and Sony A6000 have APS-C sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the A6300 and A6000 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A6300 and Sony A6000 Cameras
Sony A6300 and Sony A6000 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
DxOMark Sensor Scores

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
Sony A6300
or the
Sony A6000 ,
including hyperfocal distance.
