I don’t typically build things just for the looks, but once I’m building them I take aesthetics into account. Just the usual - picking a style that fits what I’m building (e.g. cottagecore for villager-powered farms, industrial for Thermal mods, steampunk for Create etc.), design the thing in creative mode, then build something that fits the terrain OK to host my contraption.
A bit of both.
