I don't do any slow stuff, but I think it works well for stunting. I can do 2nd gear standups like nobody's business. I have done a few stoppies here and there. I haven't found any problems with it being carbureated. Since it has a fuel pump and not a float and bowls, I don't think being tipped back causes any fuel cuts.
It has a strong powerband on the bottom too, so you can pull through while up, or get up at a low rpm.
I think it is personal preference and riding style too though.
