Personally I have had experience with the Grim Reaper Whitetail Specials, and I was not impressed with the foldback deployment style. I took a doe with one at 20 yards with a 70lb bow (28" Draw) and a Micro Diameter (.166) arrow. The Entrance of the shot, did not deploy on the outside of the hide of the deer, and the large blades didn't pass through the hide on the exit side and only the chisel tip came through the exit side. Internally it was devastating which is all a sportsman can ask for, but if I hadn't seen the deer crash, blood trailing her for the recovery would have been very poor at best. I do not believe a foldback deployment is a good efficient broadhead anymore. I like them for other game like Turkey's but will not use that style deployment again.
Rage is pretty tried and true but if you want to reuse the broadhead they are not good for that. They are built pretty thin in my opinion but their results speak for themselves too. I also have the Grim Reaper Hades Pro (Fixed blade) and that head is built very good.
Last year I took a Doe with a Sevr broadhead and was VERY impressed with those expandable heads. If you look at those (direct to consumer only) I'd recommend the harder metal (Stainless Steel or Titanium) built ones. I was able to spin test the broadhead I shot the doe with, put new blades on, and it was good as new, including the chisel tip on it.
Good luck with whatever you end on!
