I make a conscious effort to not be in the hype game, so I personally never used the 'game changer' terms. I do feel these are a very different animal than the prior/current offerings available because they include the mic/preamp timbre as part of what is offered. I hear/feel/notice and enjoy the difference greatly.
I find the sonic qualities and overall timbre far more musical and pleasing at any volume, but more so at actual gig volumes.
That said, you can take the original OH and RW IR's and make them work with EQ, Low-Cut/High-Cut just as many (most?) have been doing for years.
The major advantage here is that it takes all of that work, expertise in EQ and knowledge and distills it into an IR that is essentially a 'plug-n-play' after you choose your flavor of ice cream. Find the IR that works and go. If want more of this or that, it's often just choosing another version of the same IR and you can go further by mixing different IR's but that is - and remains - more of the advanced type of approach.
