Replying to Hellbent or Obsethed ? Please help

Here is the deal, i am riding some Obsethed(179) since one season , and i can have a very good deal on a pair of  K2 hellbent(179).
But i want to know if there is any utility to have a pair of hellbent  if you already have a pair of obsethed?

I was using my obsethed for everything from pow to rail .And if i get the hellbent it would be  for pow only.

So i would like to know if the difference between  those two ski is really noticable ( the obsethed is preatty wide) ????
