I prefer black over basalt. To me, as I have said previously on this board, basalt has an identity crisis - doesn't really know if its black, or if its dark gray. It also looks like someone scattered a teenager's glitter face paint on the surface. Nothing can touch the warm, deep color of true black. If you have the time to maintain the paint then I recommend you go for it. You'ee see EVERYTHING dust, hairline scratches, dust, dirt you didn't even know existed, etc.
