Cool, I'll pick some up.Quote

Vertical line artefacts on flat surfaces when the layer height is an exact number of full steps may be caused by low-current microstepping issues. These are common when using DRV8825 drivers, but A4988 drivers can suffer from this too. TL smoothers or equivalent (2 pairs of back-to-back diodes in series with each phase) will help with that.
Is there a feature-rich slicer that you'd personally recommend? I'm using Cura 3.2.1.Quote

If the vertical lines occur only on curved surfaces, then that's an issue with either the STL model having too low a resolution in the first place (i.e. the plane segments used to approximate a curved surface are too large) or a slicer issue.
The one on the cylinder is a layer change seam. You can choose in the slicer whether to have a seam like that or to randomise the layer change point. Layer change artefacts are difficult to get rid of, but you can experiment with the following:
- printing external perimeters first or last
- pressure advance amount, or coast to end amount in the slicer if you are not using pressure advance
- retraction on layer change
Not sure, how would I find that out? Anything in here?Quote

I think you may also have a small amount of Z banding. Are you using PID or bang-bang control of the bed heater?
