Cheap shimano one while it does the job, it's not exactly the smoothest.
the best are the White Industries one.
used shimano free wheels for years, bmx racing/dirt/street as well as singlespedd and they have always been fine and dandy, would never describe them as unsmooth, give a little spray to cut through the grease and they are sweet.
