Options. For example, I’m not thrilled with the default music player. What can you do in windows? Well, there are a few free options, but you can never really get rid of Windows Media Player. And only one or two do everything you need. In Ubuntu? Just open up the Software Center, search “Music” and I’m presented with a couple dozen of options. All free and all work pretty darn well. So I install all of them (it’s my process) and play with them, uninstalling the ones that just don’t do it for me. Eventually I’m left with one or two that I really like. And it’s the same for every type of software. Need a movie player? An internet browser? Word processor? Tons and tons of options and you’re not stuck with anything you don’t want.
