Help Macbook Pro 2013 or Macbook Air 2015

[Reflej0]

Hello, thanks to this post, where I was convinced to buy the 2011 MBP and received answers about why not buy it.

I decided to add some money to my budget, and now there are these options:

1. Macbook Air 2015 13" I5 1.6 256GB 8GB.
2. Macbook Pro 2013 13" I5 2.6 256GB 8GB.
3. Macbook 12" Core M 1.2 256 256GB 8GB.

They are not particular options, so I did not include battery cycles generally range between 100 and 300.
I know that the Macbook Air 2015 has a better integrated GPU (HD 6000) than the 2013 MBP (Iris 5100), I also know that the MB Pro CPU is a little better than the Macbook Air, and that the screen resolution is higher in the MBP
But I wanted to know if they knew anything in particular to rule out any of the options.
In addition, an MBP seller announces that it has a defect known as "staingate" that only comes with the screen off, I wanted to know if they knew this and if it was important.
Thank you !

I have a late 2013 13" Pro and an early 2015 13" Air. Both have 8gb and both are nice. I only use them for email, office apps, surfing the Internet and prefer my Pro when at home for the retina screen and Air for travelling.

If I have to choose one, I'd take the Pro.

Finally I acquired a Macbook Air 2015 13" 8GB 128GB with only 103 cycles at 40,000 AR $ (635 USD).
I am happy with the purchase, it goes super fluid.
Thanks for the help.
