Different people have different opinions. Trying to lumping people into discrete categories based on their affiliations, isn't terribly practical as you end up generalizing one characteristic across a group of individuals and get a *very* distorted (and terribly incorrect) picture of what people actually think.

As an example, if you just take Apple fan to be the moniker that represents an individual, you may expect the person to be a fanboy that hates Android, spends a lot of money, dresses like a hipster, or whatever else the stereotype is. However, being an Apple fan is just one characteristic about a person, and does not speak loudly about the other characteristics that that person has. I know people that and Apple fans that also like Android, dress poorly, dress well, are smart, are dumb, spend recklessly, are financially bright, etc.

So in short you are likely confused because of the assumption that people gauging the A8 class of processor as being adequate or inadequate have one 'voice' as they are affiliated with one 'group'. This would seem confusing as one person of the group would say 'I love it' and another of the same group would say 'I hate it'. But consider the fact that they are simply distinct individuals voicing different opinions.
