Yes, everybody is different, so the short answer is whatever works best for you.

Good layer adhesion is more important than layer height.

I would stick to the rule of thumb that the layer height should be 60%-75% of nozzle diameter. If you have a 0.4mm nozzle then I would suggest 0.25-0.30mm layer height, minimum of 3 perimeters, and octagonal infill maybe 25% and you should be good.
