That is a bit of a tough position. I will way the Asus has a better build quality in my opinion. If you are worried about performance and performance only - I'd just look at benchmarks and pick based off that.
Also - check battery capacity of each. I believe the Asus has a larger battery but unsure as I didn't dig too much.
Even if you're going to be plugged in a ton, having a poor battery would be annoying - for some.
