It just goes to show that SN808 just isn't future proof and it wouldn't surprise me if performance was noticeably slower in some current games, especially if they render at 1440p.
Depends on the game, and not all users are the same. Also the most popular games have
****** graphics, if it runs candy crash and the latest angry birds its fine for like 90%. Also rather an S808 with good battery life and no heat issues then a toaster like the S810, they can't get the latest samsung silicon so there isn't a huge amount of choice.
Also all the reviews for the LG G4 have been good, not really heard anyone complain so it should be okay. Benchmarks in there nature are meant to stress the SoC more then it would normally.
Daft would be not knowing the Moto X Style 16GB is £359 on their website while you can pickup a Galaxy S6 32GB for £362(According to Google).
Prices are close enough, gaming is great on my Galaxy S6 and Shield Tablet.
The S6 is £499 on Samsung sites, not exactly fair to compare the Moto X style against questionable 3rd parties.
