Dissing your bias? That seems counter-intuitive....
There is a difference between objective and subjective weighted criticism. The Android Central one is even worse (IMO as far as opinionated) than the one linked here, but at least goes into more detail.
For others, go buy your One's or iPhones and enjoy them
Good products as well, but do not impose standards of judgement based on personal preferences. That ain't being too scientific.
It does seem though that Samsung might have polling/cpu/memory address issues with all the darn sensors the S4 uses. My advice is turn the things off to conserve battery and not have performance issues. Most of them IMO seem like gimmicks. Notice I state "opinion" and am NOT implying a standard.
