A major reason I think HALO failed as an effective compositing app was 
the lack of effective rotoscoping tools, a good 2D tracker and paint. 
The rotoshape op looks much better now but you still need a tracker and 
paint to do bread and butter compositing. If it had these I would have 
give it a chance. Most of the other nodes are really quite good I think. 
It would be so nice to have a paint node!
