There seems to be this mistaken impression that, just because the Crown is easy to tinker with, you're somehow compelled to. Not the case at all. Mechanically, Crowns are actually pretty simple, elegant, and actually not much different about them from any other airgun. The barrels attach the same way, they have a regulator, bottle, plenum, and spring tensioned hammer. What FX changed wasn't the basic architecture, it was the accessibility to it. Now the hammer spring preload is easily adjustable with a knob. Don't like it? Don't turn it. The transfer port hole size is another easy, and more common, adjustment. And they put the reg in an accessible position so, again, you can easily adjust it. It isn't fundamentally different from say a RAW in that regard.
As far as accuracy goes, I'd argue that all the "premium" brands out there are really likely a tossup. Both have won competitions (EBR) and can shoot sub MOA on a good day. Out of any two rifles and one may be better than another, but that is just chance as some guns will just have better barrels than others. You'll see this go both ways, someone will claim one was more accurate than another, and someone else will contradict them. I've never seen a shred of aggregated data to suggest one brand is actually better on average than the other.
Keep in mind that world class competitive rifle shooters typically go to who they believe is the best barrel maker, and order half a dozen barrels. They then shoot each of them and pick the best one for their competition rifle. (often harmonics tuning is part of that game as well) If having THE BEST accuracy is your game, I'd give the edge to the Crown simply because you can lathe fit a normal Loather Walther (or whoever) barrel blank to either gun with the same amount of effort/cost, however with the Crown you can also quite easily just pick up half a dozen liners and swap them picking the best with little effort, and/or picking different chokes and twist rates. I don't think it is necessary unless you're looking for tenths of an inch at 100 yards, but if you were looking for the absolute maximum accuracy, that is how you go about it. To be fair this can cut the other way though, you can fit an STX barrel to a RW, at least one gentleman on this forum did and was very pleased with the results, but it is more of an involved process.
The one performance thing with the Safari worth noting is the lack of a regulator. Despite being ostensibly "electronically regulated," the air delivery will vary substantially from shot to shot. This can actually be seen in the sound signature of these "self-regulating" (hammer regulated) guns. This can change muzzle turbulence, pellet BC, etc throughout the shot cycle. And it is a known phenomenon, even acknowledged by Daystate. It is also one of the primary advantages of the Delta Wolf.

You could almost purchase THREE Crown VPs for that (1,350$ each). That is certainly something to consider.
Full disclosure, I own not one but TWO FX Crowns, one running the factory 80FPE tune, the other 32fpe. Love both of them.
