Choice and flexibility are the hallmarks of the Linux ecosystem. In Windows and OS X, if you don't like some aspects of the operating system, there's not much you can do about it.
Not so in the Linux world, where thanks to the numerous distributions you are in fact spoilt for choice. Each distro has the Linux kernel at its core, but builds on top of that with their own selection of other components, depending on the target audience for the distro.
Different distros offer different customisation options, so you can fiddle around with the distro and customise it as per your taste and preferences until you get the kind of thing you're looking for. So no matter what sort of user you are, there's a distro for you.
