Netgear wax220 or GL.iNet Flint 2 GL-MT6000

I am upgrading wireless in a 2 story home.

The Flint 2 has external antennas. If I read correctly, it covers an area in a horizontal donut perpendicular to the antenna, good for the first floor that is open with limited or not walls.

I am thinking about getting a second Flint 2 for the middle of the upstairs. Or would it be better to get 2 wax220 for 2 bedrooms at opposite ends of the house?

Two cap would be better, check other modela with 2.5 gig eth
