I have a window AC installed and although installing it appears more messy as you will need to break or trim the window/wall to fix it, it's actually easier to install! Since the compressor and fan are right on the window it makes more noise.
The noise can be very annoying, especially at night. And you;re right it looks messier! The split air conditioners need just a small hole in the wall and a few nails or hooks inside the house. posted by

I find that window air conditioners are cheaper than the split air conditioners where the compressor and motor are outside and only a more compact unit is inside. The window air conditioners do not need a long tube unlike the split air conditioners.
Casement or window air conditioners have all the parts in the unit which is attached to a window. the compressor, unit, air intake, cooling coils are all inside the box-like enclosure.
