What you say is only an assumption. And if it's true, then I wonder how Android actually got the better user experience lately. I have access to all of iPhone 4S, Samsung Galaxy S2 and a Galaxy Nexus. For me both androids are quite a lot better than the iPhone (disregarding the industrial design which is best on the iPhone). And I actually have a hard time deciding between Samsung's modded version and the original Android on the Nexus.

Note: Of course, I probably fit into the category of power users. Knowing which apps to disable, which to install, and which to configure (and how) is a good thing to know.
