Good (free) drawing program for my laptop?

I have an HP touchscreen laptop and wanted to start digital drawing / painting.

I'm currently testing out Medibang and Krita. However, I don't like either of them because I'm missing certain features (or I don't know how it works).

I'm looking for something like Procreate. When I paint something, it should automatically be straight or smooth like with Procreate, on Medibang and Krita my lines are not automatically straight but as wobbly as I draw it.

Could someone suggest me something good? Doesn't have to be free, but at least a trial version should be available.

I don't know if this is also available for your device, but I definitely recommend ibisPaint.
