I was avoiding displacement. It adds a shit ton of messy geometry at render time and I mean messy! If you try to get in close it looks like total shit! To tame the jaggies you have to smooth the model a gazillion times. Displacement is just a horrible option to be avoided at all costs. I have used it to model embossed text but only because modeling inset text would be a nightmare. For raised text I would still choose to render it seperately and stuff it into the surface or use bump.
