Agree. After reading all the post, especially those by aspire2oo6, I wish to make some comment.

Although all this while I dislike iOS, but I do acknowledge it pros over Android. For my friends who doesn't like to / have no knowledge in customizing, I always advice them to get iPhone instead of Android as it is easy for them to use and the learning curve is not too steep and the apps support is much better than WP. But the restriction in iOS will never make me to choose an i product anytime for the time being.

Android ever since JB is pretty lag free, thanks to the project butter. Most of the time it's only the OEM launcher that slow it down, just a bit. A simple tweaking, even without rooting can solve all the issue by installing 3rd party launcher, which is free and highly customisable, like Nova or Apex. If you have the time and interest to learn about rooting, basically an Android device is more like a pocketable simplified laptop which you can do ALMOST everything with your device.

As for iOS vs Android there are already plenty of article and discussion if you google about it and we don't have to waste our time debating here. But associating rich and powerful people with iOS is accurate. Most rich and high profile people are busy and they don't have time to play with their phone, hence they choose the easiest phone to use. I'm working in an MNC company, and most of the top management and expatriate they use iPhone for email and callign purpose. But during holiday and weekend, they always toy around with their Android devices.

In conclusion, there is no single best OS for the time being now. Just choose which OS work best for you and invest your resource and time in it.
