Ghostbusters, Ubuntu is more stable, more lightweight, less resource hungry, community driven - so they only include the features people actually want.

And its way of installing things through the ubuntu software centre is just inspired. You search for a program in the search box and if you want it you click install. It does all the rest. No more waiting for an exe to download then running it yourself, then unticking all the included crapware. Everything in the Ubuntu software centre is approved by them.
