georeferencing - How to exactly georeference in QGIS


When I georeference a raster image in QGIS, it's always a bit displaced as in the attached image (the cyan polygon is the template, the red border is the georeferenced image), although I try to set the georeference points as exact as possible.


Is there a trick to set the georeference points more exact or maybe move the raster layer a bit? Maybe there is a different software, you can georeference by moving and then import it to QGIS?enter image description here

I have good result changing the default transformation settings from Linear to Helmert.
