the best graphic...
i would say any 2d psp game...
and most if not all, the first party titles.
for 3d psp game, might only be slightly better on vita, but not much.
at the end of the day, its just upscaling, a little bit of color correcting and a better smoothing/anti-aliasing.
the texture for the 3d, will just be the same, the same old low resolution texture..
since its not a remastered or anything.
if you want a better looking one, just might as well wait for the new games created especially for vita,
especially those AAA titles...
could be a long wait friend...
my advice, just enjoy the game... don't think too much about them graphics.

True, putting too much expectation on the VITA will ultimately dissapoint but what I've seen so far from UC:GA does not dissapoint and almost impressive for a portable to run.
I'd say the VITA will give a run for your money if you leave out it's flaw and issues
