Triple 7 master race. There's seriously no better airliner for long distances.
Almost CFI here. Trying to get time and liscences to fly charter.
The 777 is probably the best long-range aircraft right now. I'd say I've had some pretty good experiences on cross-country flights on A320s and 767s, though. They're both comfortable planes, but yes, I do believe the 777 is amazing for long distance. However it's really kind of ugly. It has that almost cylindrical shape at the front and isn't very sleek.
The a380 may be one of the ugliest planes I've seen in my life, but damn it looks and performs well.
