I put Quartz counters in my galley several years ago. I also have it in my home. I see no difference between the environment of my galley and my kitchen, so no reason to be concerned about the choice of counter surfaces.
In both places there is frequent sun, frequent periods of abandonment, hot objects, things that might stick, stain, otherwise threaten the surface. In both I have no issues whatsoever.
On Quartz v Granite, the suppliers told me that Granite needs a sealer, while Quartz doesn't, so that made a difference.
