Messed up, posted wrong clip (the one with games, which the 6S loads a bit faster). There are several with apps and web browsing, where generally the P9 does a bit better, with the notable exception of Uber which loads slowly on Android for some reason. Anyway at half the price and with better screen/camera/battery/etc.
E.g.
And I mean, the P9 is really nice, but there are so many high-end Android phones to choose from (S7, Nexus 6P etc). I wonder if the Note 7 is going to be cheaper than the 16Gb 6S. If I were in charge at Samsung, that's exactly what I would do, just to point out how staggeringly bad value the iPhone is.
PS: answered my own question. I wasn't aware that the Note 7 has already appeared online here in Switzerland, but it has, at CHF828 (64Gb memory). The equivalent 6S plus is CHF999. Paying a lot more for a lot less, that's something.
