Laptops with 980 GPU

[verte200]

Too keep this short, I have $2600 from my previously sold laptop and knew the 980ms were going to come. I need one for school and gaming. So far I have noticed the MSI GT72 series and the Asus G751.
If possible, I want to know:
Which is better for batter life?
Which has a better screen?
Which is better on performance (I personally like the style of rog, but would buy what ever functions better)?
Which has better read and write speed?
Which has better audio?
Which has better cooling?
Basically which is overall better. I have never used a MSI machine so I have no clue how there like either.

All the CPU's have very little difference for gaming purposes.
MSI laptops in general have great cooling and overall build qualities, I cant really speak on the audio aspect.

This version would probably be the one I go after:

Does it have good battery life though?

Has it rated at 4+ hours, but that count is not taken in during gaming.

So overall it is a better laptop, right?
