Perfect proportions, tough but graceful. Even the wingtip antennas add something to the aesthetics. The 747-400 is still a nice-looking plane but the longer hump makes it look a bit more hunchbacked.

Stubby, too squat and fat. The engines do not match the plane; if I remember right these engines were developed for a tail-mounted configuration and were then later just slapped on the 737 when Boeing realized airlines wanted a plane that was actually smaller and more fuel efficient than the 727. They basically chopped the 727-100 fuselage down a few feet and slung the engines below the wings. The result is the aesthetic mess that is the 737-100.
Now, the 737-800 is not that bad-looking of a plane:

The longer length, redesigned engines that look like they belong under-wing, and redesigned tail make all the difference. It's still not beautiful, but it's no longer an ugly duckling.

I don't consider any Airbus model particularly sleek, but this is about as good as it gets for them. It's graceful, at the very least - though a bit on the generic side. Looks like a grown-up 707.
The longer versions of the A340 are too long, and the more powerful engines look too big for the plane. The A343 is well-proportioned.

Yes, I realize the airplane is not finished in this pic, but we've all seen the 3D renders and other renditions of the finished plane in various liveries. It's ugly. It looks like a giant pig. And it's all out of proportion; as big as the fuselage is, the wings look too big for it. The tail looks too big for it. It's like a mutant 747-SP, but without any of the
SP's distinctiveness and charm.

Enough said.
