Let's face it, all rubber grips are ugly. Some are uglier than others (Pachmyr). However, I have rubbers on all of my magnum revolvers for the simple reason that they are far more comfortable than non-rubber grips. I've always been particularly fond of Pachmyr Decellerators and Grippers, because they fit my extra large hands well and because they cover the backstrap, thereby minimizing the effects of recoil.
Hogues? As others have pointed out, Hogues don't fit everybody's hand equally well. I'm one of those whose fingers don't line up with the grooves on the rubber grip. I take a very high handhold and, unfortunately, that causes my fingers to rest on the points rather than the grooves.
These new grips look intriguing. They remind me a little bit of the old and, sadly, discontinued Uncle Mike's. I'd be really interested in them if they completely cover the backstrap because for me, and exposed and a covered backstrap make all of the difference from unpleasant shooting to total comfort.
