between the two i would say muzzys have a better track record, i know a lot of 'old' guys that swear by em haha. I just started archery about a year ago, so i wouldnt have much experience in this detail but i asked the guys at the local bow shop and they recommended:
fixed blade:
shuttle t lock
muzzy 3 blade
mechanical:
ram cat (hybrid mechanical)- this is the one i use, i havent shot anything with it yet but they fly pretty well. These are actually pretty cool because they are sharp on both sides of the broadhead.
G5 mechanical
They didnt mention much about the rage broadheads. To me they look good, i saw Tom Miranda take a grizzly with a Rage titanium 2 blade on TV so i would say they would be another good option
