I have shot muzzy for 20 years, dont see a need in changing. If a broahead does what you want it to do, why change. When I first started bowhunting many years ago there were very few broadheads on the market. Bear razorheads and magnus were the mainstay. I remember when they came out with the satellite broadheads. I started using them they had a couple of bad faults to them. One they didnt fly all that great and second the blades had a bad habit of coming off inside the deer. I remember finding several arrows after passing thru a deer and there would be 1 blade left or none, if you were lucky enough to even find it. Had to be very careful when cleaning a deer not to cut yourself. Been many improvements in broadhead tech in the last 30 years.
