I have no spacers under my stem now. It s not only for the look of it. If i set my stem level at the top with the spacers down i feel like a pain in my back(it may sounds dumb, because usually ppl feel comfortable) but i feel more confortable more stretched. Ps. I know i will feel very uncomfortable on climbings when i will not use my seat. Grinding on climbs will not allow my back to be stretched upside and comfortable.
