Mine is direct drive. I could have gone with belt drives but it was no more expensive to buy larger steppers than three pulleys and belts. Motor guards were easier to make too.
If I had more room in my shop I probably would have gone direct drive because it is simpler to do. I used belt drive on the X & Y to keep the overall envelope of the machine as small as possible. With the belt drive I like not having the stepper hanging out front. The motor covers a a little more complicated but I like the way it turned out. It also keeps my coolant enclosure smaller.
