The average G-IV trip is not 4,200 NM. The average G-IV trip is precisely what everyone else is doing: 1200-1500 NM. Ignoring that, let's just call it NY-CA. That is the average trip for a G-IV. They are not going LAS to Europe on average. For crying out loud, the G-Strings are doing exactly what the Legacy(s) are...I see the same tail numbers over and over again.
When you need to go 4,200 NM then go in rented G-IV or make a fuel stop with the EMB on the rare occasion you go that far.
Gulfstreams regularly (NOT rarely) go from the East Coast into Europe and from the Midwest into Europe... Both of those trips would require a fuel stop in the WSofD... How about from Anchorage down into Asia? The WSofD would require a fuel stop in Russia (and get to use their "wonderful" runways!) PANC-RJBB, G-IV non-stop, no problem, WSofD would be swimming the last few hundred miles, but hey, at least they have a big coffin, I mean cabin...
Here are some "typical" trips that G-IV operators I know do... Yeah, they do run domestically also, but when it is time for the International stuff (which nearly 50% of their flying is) the G-IV can do both missions equally well... The WSofD might be a decent Domestic airplane (IF you have adequate runway), but it comes up way short in the International arena...
