I would stick with the smooth surface. I have built a couple tables this way and have excellent results. Keep in mind that at times you need to be able to pencil a reference point directly onto the table. A quick wipe with a wet rag and its gone. I can't help but feel that anything textured would accumulate dirt and debris faster thus increasing friction. It makes sense to me that these tiny ridges would wear faster than a smooth surface. Remember that you are concentrating the weight on the ridges, less support. It may not make a practical difference either way. Let us know what you decide and how it turns out.
