Oh god please don't, they're both sub par headsets. Everyone here who has had the misfortune of buying one says they would not recommend it. 
Index is the gold standard. It's the best all rounder - the screen is a couple years old now so there's better screens on the market for pixel density (the HP G2 is the better one) but for the entire package it's the best. 
Even with the controller and cable issues.
