Lees Ultimate vs Python

Is there any difference between Lee's Ultimate Gravel Cleaner and the Python system (other than the "claw" on the Lee's)? From what I understand, all the parts are interchangeable. Obviously Lees is blue, Python is green...anything else?
As previously mentioned; due to the claw on the end of the vacuum and the cheap constructions of most of the parts the Lee's Ultimate Gravel Cleaner does not work nearly as well. Don't waste money on an imitation; get the Python.
