What's the difference between these 2 skills of pilot?

Which skill should I choose among these two?

Pilot Perks Notes:

+50% Aircraft detection range = Increases the distance at which the lead indicator (Identify distance) and the triangle above planes (Detecting range) appears
Math = Identify distance - 1000m → 1500m
Detecting range - 1500m → 2250m

+30% focused/peripheral angle = Lets you detect enemies around you in a sphere around the plane, between 15° & 60° is the peripheral vision, which halves the detect/identity distances -15°/15° is the focused vision which has the normal distances
Math = Peripheral - 60° → 78°
Focused angle - 15° → 19.5°

From Enlisted Resource
The detection range one is the superior one, but if you have spare points, you should also put them into vision angle, AI gunners beneffit from it.
