I hate to sound like an advertisement.
But having just bought a new phone from an "obscure, irrelevant" Chinese OEM -
Specifically a ZTE Blade S6
I have to say it pisses over this Samsung.
£170 from Amazon.
A 615 processor instead of 410
2GB RAM instead of 1 (makes a huge difference to multitasking & performance compared to my old Moto G)
Android 5.0.2 instead of KitKat.
A non-pentile 720 screen.
Sure, it's plastic, but I have come to the conclusion that plastic is actually a better material for making phones from than metal and glass.
