In both worlds it has always been about doing more with less, largely in part to improve battery life. I definitely wouldn't say "years" behind but behind in certain areas?... perhaps. Both sides are when you look at the whole picture. It's not about choosing a name or even about choosing performance while sacrificing everything else: it's about choosing the right phone for your individual needs. Personally, the GS2 has far exceeded the iPhone 4 in all areas that are on my "need/want" list. Is that the same experience for the next guy? Absolutely not. Does that make either better than the other? Again... absolutely not. Sheer numbers are just that, numbers. Give an iPhone to a guy who absolutely requires removable storage and he ends up with a completely useless device.
