Of course faster access times and smaller size. It is not important to know the exact distance to mate when you are winning unless you have problems to win won positions but the main advantage of tablebases is not in winning won positions but in transition to won positions and programs can use tablebases only at the root and use only bitbases in the search when they are not in tablebase position.
