I use a Python daily at work and I have to say I think that the Aqueon's pump is a much better design then the Python. I like the valve switch on the pump rather then the Python where you have to pull the bottom of the pump down and turn it. We have gone through a few pumps in the last couple of years. The one downside I see in the Aqueon is the size of the gravel vac tube. Depending on the size of your tank you might want to look into a longer tube. Just my .02.
