For objects created from a circle - like a sphere, cylinder or cone - it’s usually best to set the segment count for the circles to a multiple of 3, and 4.
So 24, 36, 48, 60, 72, 96 etc.
This means that they are easily manipulated in 3d, and nodes fall logically.
It’s also counterproductive to make too many segments, as the facets generated increase disproportionately and offer little visual benefit for smoothed objects whilst overloading the model’s geometry, shadow handling etc.
If you are intending to 3d-print, then choose a segmentation which makes edges within the printers minimums, having more geometry that that is of no benefit. See ‘versines’…
