The Super Jet is definitely the best filter on the market, not just for aesthetics. Best for the price point? Well that's something that is up to the individual. It does include filter media, lily pipes and clear hose, which helps make it more cost effective (so a $550 Super Jet, is actually about $280 for the filter itself).
Standard protocol for filtration gph/lph calculation is the filter empty and running, so flow is usually cut in half just by adding media.
However, the Super Jet retains about 90% of it's flow even with media in it and after running for months. Mostly because it is powered by an Iwaki external pump as opposed to an internal pump made out of plastic that gets clogged easier.
