Powerizers are exactly the same as Projumps, powerstriders, flyjumpers and well a tonne of others. They are made in the same factory.
Simple answer to your question would be yes. People flip and get great height on them. When you get other brands (from different factories) you pay for spring responsiveness which basically means it is easier to get the height and the spring reacts faster to the energy put in. Most people upgrade after some time. Depends what your budget is really but if you are in the uk and you are gonna get "powerizers" then you may as well get projumps. But I know they have a lot of spring weights out of stock at the moment.
I have projumps and I am really happy with them
I cant flip yet..but I am determined to do it
