Honestly, I'd take the one with crappy models but great sound and icons over the one with great models but crappy sound and icons. Having lousy models makes a model amateurish and lackluster, sure, but bad sounds are almost painful. There was an RPG I used to play where every time you selected one of your characters, they'd say their selection sound, but they each only had one or two, and after a while it got so annoying that I just disabled the sound. My point is that neither area is necessarily more important than the other, since it all depends on who you ask and where their priorities are, so that's why I support the 0-10% rating for each area.
On another note, how should we score an area that is just a compilation of stuff from other mods? Give it a 0? Give a 5 (neither good nor bad)? I guess the question is: Should "nothing new" count as better or worse than "new, but horrible"?
