Help Which Zenfone do I get?

[stl522013]

Ok, so I am on the fence between the Zenfone 2 Laser ZE551KL and the 2 GB/1.8 GHz version of the Zenfone 2. The Laser has an IR Laser for fast focusing, a removable battery (they both have 3000 mAh Li-Pro batteries), 3 GB of RAM, and an octa-core Snapdragon 615. Other than that they are both pretty much the same. The lower end Asus Zenfone 2 has a quad core 1.8 GHz Intel Atom, 2 betterAM, and a non removeable battery. I know the Intel has better single core performance, but IDK about overall performance. Where could I find some benchmarks? And which do guys think is better?
