The Defiant also gets a hugely-overrated rep for being a "utilitarian" design when there are a lot of silly choices taken with it (oh, your heavily-armed cannons are strapped to the front of your warp nacelles? I know what I'm aiming at!)

There was some beautiful concept art for the Defiant that still kept the compact vertical profile, but they seemed to go with the one that looks like a part missing from a He-Man toy. Shame.
