You need to understand two *very* important things when looking at that site:
1) all of those items are entered by other users. It looks like I could enter a "Pro" saying that the S5 was able to wipe my **** for me. One of the items listed even says that a completely different Android phone has a better camera lens than the S5, listed under the S5 "pros".
2) several of the items listed are just plain wrong. Several of the "Pros" listed for the iPhone are also on the S5, like being able to locate a lost device or lock the phone, or turn-by-turn directions. The "dual-flash" item shows that whoever entered that doesn't even understand how Apple's dual-flash setup is supposed to work. Also, the Note 2 and 3 and (I believe) the S4 record in slow motion. My Note 3 (like my Note 2 before it) actually records at 240 fps.
I mean, this is actually one of the "Pros" for the iPhone from that site:
Just it feels perfect! Yes vs No I love my iPhone!!!
That should sum it up. That looks like a horrible site. I would recommend not using it for any kind of research.
EDIT: Did this thing really just filter a four-letter word for my rear-end that starts with a "B" and ends with two "T"s?
