I thought its opportune to start such a discussion also about the 777 as the basic two versions have a very different aesthetic appearance to me.
The 777-200 is very pretty:

although very sensible to the livery applied. Egyptairs 772s aren´t very nice-looking (thankfully they will be dumped for Airbusses soon)

The 777-300 is a very odd-looking airplane that looks like some airplane-nerds photoshop-experiment unfortunally making it into reality. I´m looking forward to some nice pictures of this type at Mojave soon.
