They are 'objectively' the best looking of the 3. There are a few slash weak enemies, but you should realistically be using a scythe for those anyway. At this point, what dryores you buy is based on whether you like the way they look. There is no monster/boss in the game that is weak to a specific melee style (except for KK but you should be using the Keris anyway) that you don't already have 100% accuracy on using any of the three sets. In the distant past, the maces *were* less dps (about 1%) than the longswords and the rapiers, but that has been changed long ago. I personally use MHM+OHL because I like the prayer bonus of the mace and the looks of the longswords. I honestly surprised that the rapiers aren't cheaper than maces at this point since they don't really have any advantages going for them. I personally don't like the look of rapiers, and most people I know much prefer the look of the longswords or the prayer bonus of the maces.
