I don't like it personally. I typically use 45min, 20 min, and tape mud. A few places I have done require a very smooth even finish and that's pretty hard to get with the low dust mud for me. Plus, hot mud works so fast I don't have to spend a week at a house getting the job done right. Houston had so many drywall jobs from the hurricane last year that you could work nonstop just on drywalling. There are still people that need drywalling done down here from that storm.
