Although the Nutribullet pro 1000 feature is more powerful than the original, it doesn't do a great job of liquifying frozen fruits and spinach like the original .I have used it almost every day for the past few weeks and there is still lumps and bumps. Turned it on for 30 seconds, turned it off and turned it on again for another 30 seconds hoping it would liquify but it did not help. 

The extractor blade is much easier for cleaning but that is the only improvement.
