I have been thinking of which is better, as, it is 2000 in world 1757 and we really want to fly a plane from our eastern hubs to far-away Asian airports like Singapore and Jakarta, but with the A345 coming soon with the only range to reach these airports and the 777-200LR coming 3 yrs later, but with more seats, so this is a tricky question 
Hopefully you're buying these for prestige only because this thing is outrageous. The price, the fuel consumption, maintenance, everything

I made like 100k/150k a day (hour) with this thing which means it'll take at least 8 years to make that 340 million back if I didn't have to pay maintenance costs, which I had to so that basically means you'll never ever make a profit out of this. But on the other hand, those long curvy routes look kinda sweet on your route map

So yes, ultra long haul, basically, is a prestige thing. Period.
