I looked at the Samsung Galaxy S2 and their tablets. . . And helped client with them. No, they were not "years ahead of Apple". . .and were not anywhere close to Apple's technology which Samsung was desperately copying. The apps on the Android tablets were merely blown up phone apps, and usually not well implemented. The user interface is still not well thought out.
I have used both side by side. Samsung Galaxy 3S and onward are fine and about as good as an Iphone, even if just a little behind. They are not “copying” Apple.
Please tell me any advantages of the iPhone 6 over the Galaxy S2 that would cause me to consider upgrading.
