Difference between one WET/DRY Filter and another???

[moy]

From what i've seen most WET/DRY FILTERS seem to be about the same size. So my question is, how is that 2 Wet/Dry filters about the same size can very greatly in difference as into how many gallons they can each support??
Is it becuase of the Powerhead (FLOWRATE),the higher the GPH the better??
I guess when i trying to do is buy a cheaper Wet/Dry filter that is just slightly smaller than a Higher Rated (Gallons that it can support) Wet/Dry Filter and put a stronger Powerhead in it. Will that help?? Will it perform just as good as slightly bigger Wet/Dry Filter??
Is there any reason why i should not do this (put a stronger powerhead in a smaller WET/Dry box)??
OR
How can i get best performance/the most out of a smaller WET/DRY Filter??
Can anyone please shine some insight on this!! Please!!!

well regardless of size, wet dry's vary in prive do to many things, the one thats off the top of my head is size, how many containers of bio balls there are, some also come with built in skimmers.. i would check out Amiracle.com to check out there wet/dry;s

So having more Bio-balls makes a Wet/Dry better than another???
