Another possibility is that the assumption that iOS is much better is incorrect.
Neither is better, I don't think some realize how stupid they sound when they choose one side and vehemently stand behind it as "better" without opening their eyes to anything else. The reality is that some user PREFER one OS over another due to the way they use that OS, familiarity, ecosystem, etc. It doesn't make that OS better in general, just better for that particular person. We can also start to pick apart each feature and/or app, but once again that is usually a function of the person and their needs.
If we could get by this then we would see some great discussion on the forums. Unfortunately we are stuck with 90% of posts being someone proclaiming how their OS is universally better.
