Better Device for emulator

[KingPepper]

Personally I would go with the first device, due to its far Superior specs, these would give you a very smooth experience, as it has 8 cores vs 4 cores.
It's streets ahead in terms of specs - Adeno 405 vs Mali MP2 graphics chip, 2 gig vs 1 gig Ram.
The games I should imagine on 2nd device would on the whole run jerky compared to the 1st device.

But let's see what other people who have devices similar to yours say though.
