That's the first time I've heard or read someone preferring a 5 point over a 6 point and saying the 5 point was more comfortable and the 6 point was the harness that was "grabbing stuff".
Obviously you have more experience than most on this board.
Not sure of the size of the belts I normally use, I've driven wayyyy too many cars lately (good problem to have). Also, I'm definitely I'm not fully aware of the difference in level of safety. Just telling it from the standpoint of what I've driven and it's comfortability. Safety > comfortability in the end.
I just know after several hard braking zones, the crossed belts underneath my crotch tend to become awfully uncomfortable and begin to pinch in some not-so-fun areas. And a little bit messier like I said.
