I have a 33G hex front tank rather than a full hexagonal tank. I like it although it definately is a bit on the tall side. The extra height is making me really consider swimming levels of my fish when it comes to stocking. I think the hex front makes the aquarium stand out more. If you're uncertain about getting something with a nonstandard shape (really, if you're questioning doing anything nonstandard), I wouldn't bother doing it unless you had a good reason. The shape definitely -does- impact the viewing.
