^^^ What he said.
While those scopes you mention are each pretty cool pieces of equipment - here are a couple of things to consider:
1) Anything above 15-18x, and you're almost certainly going to lose the animal in your scope when you shoot. Almost no animal goes down on first shot if you're doing a heart/lung shot.
2) The scopes going way above 18x have become the rage largely because of PRS games. Those go on very heavy rifles, mostly shooting light-recoiling cartridges, on targets that didn't evolve to blend into the environment. In that context, shooters actually get use and value out of higher top-end magnification. PRS isn't field realities, however, where it's easy to lose an animal in your scope with recoil, darkness, etc.
3) Those PRS scopes are chonky, heavy instruments. More mag, especially larger mag ranges, generally means heavier scopes. The places were higher magnification would theoretically help are also the same places (ie, western big game hunting) where you're going to be hauling your gun and gear the greatest distances and altitude gains/loses. Light is good, at least to the point where it becomes less reliable.
4) I have very expensive taste in glass, having been quite a fan of Swarovskis. But new information and perspective changes minds. The next hunting scope I'll be giving a shot is the Maven RS 1.2. That might say something. I don't expect it to have as good of glass or low-light capability of my Swarovskis, but at this point, subject to personal validation later on, it may be one of the most optimal hunting scopes out there.
