You seem to be a little more plugged in to this stuff than I am, but it was always my impression the bullets and ninjas didnt provide quite as much nutrition . I believe Removing that fiber like a juicer does increases the bio availability of the nutrients, which is why that fiber waste is virtually tasteless . I figure I get enough fiber elsewhere too.
I will agree though cleaning the juicer is a pain in the butt , plus if you dont remove the waste from the kitchen immediately it stinks. My mother in law came over with her ninja bullet and I was not fond of it. I am not crazy about the pulp but it did seem to handle whatever she threw in the thing which is more than I can say for my juicer.
I cave a high quality Brevile blender and it handles ice with no trouble at all, I use it for smoothies all the time, I think it was about 300.00 and has served me very well, Id suggest that over a ninja or bullet. This looks like the newer version of what I have, mines about 5 years old and still works like new.

Although this nija looks pretty damn good.
