It really is funny how one seems “more” than the other.
I noticed this when I saw both on the same menu. The menu was describing 2 burgers that the restaurant offered (amongst other items). For the more basic choice it was 8oz and the more fancy offering (which came with sauted onions and mushroom etc) it was half pound of beef.
Of course, the more basic one was under $6 and the half pound one was $7.99 ;o)
