How do i make paintbrush borders match with pixels'?

[WolfChatterbox]

I need to draw a circle with smooth edges but also i want it symmetric. I can't use pencil cuz it makes circle's edges sharp, paintbrush can make it smooth, but unlike pencil paintbrush borders "ignore" pixels' borders and for example clicking on different places of the same pixel will give you different circles while same action with pencil will give you same circle until you move your cursor to another pixel. Can i make paintbrush borders match with pixels' (like pencil do) or make pencil have smooth edges (like paintbrush do)?
GIMP ver: 2.10.12

(Sorry for my english, i put some pics to show my problem more clearly)

Try to define an image grid which is centered in pixels (ie, offset of (.5,.5)) and of course View > Snap to grid.
