This is really the DJs department.  My uplights are going to be higher quality units which means they will look better in the venue and have advanced features like changing colors along with synchronizing to the music.
Other than DJs (those of us that keep up with technology that is) most other people use older style lights with lamps.  They are cheap, stay one color, not very vivid, big, get really hot, and are just basically ugly.  I am meticulous about the placement and spacing of the lights - others are not.  I can control the feeling of the lights with the music during dancing - others can not because they just turn them on and leave.  Not to mention that if a guests hits one and knocks it over, no one will be there to reposition the light.
