The Snapdragon 808 was definitely a better choice. The 810 is a disaster of an SoC. Throttles to about half the speed of the 808 and it still gets hotter. Even the 805 performs better in some situations, and without overheating. It's no Exynos 7420, and the 808 has a weaker GPU than the 805, 810 and 7420, but as long as it doesn't lag, it should be fine.
