Personal preference but I went flat for mine even though I have texture on the ceiling throughout the rest of the house. If you plan to do any soffit rope lights or LED lighting a flat ceiling would look better as the lights would highlight the texture.
Machine brocade which is similar to ceilings in rest of house..................the house walls have heavy skip trowel which matches quite well.
I've used Ralph Lauren Suede paint which is leather type texture................absorbs light quite well, and is extremely dark with lights turned off and with lights on provides a welcoming environment for reading, listening to music......etc.
I went with textured for the reasons already stated. It helps to hide flaws in both the drywall and paint. As noted the flat black paint will scuff so easily it would just drive me crazy if I was having to touch it up constantly.
