It might be an unpopular opinion, but I think much of the new improvements in amp modeling (within Fractal) are very gradual. I'm glad they are always pushing forward, but the difference in X3 modeling to the current algos might be almost imperceptible to most players. Slightly different, but not a major jump forward in realism. And I mean that as a compliment, because the truth is that it already sounds and feels extremely good and close to the 'real thing'. Again, I'm glad Fractal is ever evolving, but I'm more eager for user enhancements and new features like gapless, and dyna cabs etc, than putting a scope on a new amp model and zooming into the graph and saying see that there, that's just a bit more realistic. I'd wager most musicians (especially old rockers like me with tinnitus LOL) won't notice an appreciable difference. In my opinion, Fractal modeling is already so good, it's passed that blindfold test against real amps a long time ago.
