Sumps are like underwear;
Some buy the utility brands at Walmart while others go to New York City and purchase designer fashions.
All of them serve a similar purpose, some are better fitting, some are more eye-pleasing, and some are more utilitarian.
Lots of folks don't wear any (they go sump-less in this analogy), and in the end it all comes down to what makes you happy when you go to hide your water handling and waste filtering equipment. I think it is a good idea to hide my equipment, so I have a utilitarian sump that keeps all the heaters, junk, hose rolls, pumps, ect. kind of hidden and tucked away.
I used to use all the low price stuff myself, but I've seen some really hot set-ups with designer builds that look really nice. They are easy to look at and easier to visually appreciate.
If you want to keep your reef for a long time having beautiful equipment isn't a bad upfront investment.
