My reflection went immediately towards displayability rather than look of the ship. I always loved the UCS Super Star Destroyer which is, in my opinion, one of the most stunning Lego models on display. A Nebulon-B (long and narrow) would similarly look very displayable on shelves. On the contrary, a UCS Republic Gunship would result far too big for shelves and generally hardly displayable, requiring a large surface (e.g. dedicated desk/table). The latest system scale version was already 48 cm long and 43 cm wide, which is perfecty fine size.
