Thanks a bunch, it means a lot!I jump back and forth between brands, but I always use pens. In this image I used Faber-Castell PITT artist pens, but the ink is prone to fading when I rub an eraser over it, which is inconvenient since I always begin with a pencil sketch... I've also used Sakura Pigma Microns and Prismacolor Premier Illustration Markers (they call them markers, but they're pens to me >.>).All of them are great for ink work, I encourage you to try them out and see which ones mold best with your style.
