Lug nuts are usually easier to use than lug bolts when you change tires, because you can hang the wheel on the stud and tighten the nut instead of aligning the two sets of holes, which lug bolts need to do. But be careful of damaging the threads on the wheel bolts, as it is difficult to replace the bolts. On the other hand, if a car with lug bolts has a damaged bolt hole, you may consider replacing the entire wheel hub.
