Agree 100%. Wasn't the question asked by the OP however. He didn't ask, "Which sounds better?" He asked, "Which is the better value?"
In fact, screw HALion 6. Wait for Absolute to go on sale and get that. It comes with HALion and a whole bunch of other stuff including pianos. And Absolute, on sale, costs less than Omnisphere. In fact, I got Absolute for $300. That's $200 less than Omnisphere which never goes on sale.
Now THAT'S a real value
