----> = arrow
> = greater than sign

Actually I see far more people use > as an arrow (usually discussing SCs) than use ----> as some type of greater than.

If someone wants some type of extremelly greater than they would likely use this:

FFXII >>>>>>>>>>>>>>>>>>>>>> FFXI

to express that FFXII is waaaay greater tahn FFXI... though that could still be used as an arrow commonly /shrug
