No it's not. Look, MG didn't use a comparison of a Toyota to a Honda -- brands considered to be on equal footing. He likened the iPhone to a high end brand (Mercedes) and the Nexus to an economy brand (Honda).
This is not a comparison of equals, but a comparison of Luxury vs. Standard. That's no longer about preferences, that's about one being better.
No, he didn't compare the iPhone to a Mercedes and the Nexus to a Honda, at least not as flat comparisons. Read it again. He was explaining that to an iphone fan, ICS still does not have the same level of "polish", even though its features may be great. He gives examples, such as: how you have to click again to type in text fields, even after you've selected them; pages not rendering correctly on the browser; tap to zoom not working quite right; occasional stutters in the UI; crashing apps.
