Adaptive Display vs Basic

Probably Basic. Adaptive display lets the screen get brighter when outdoors, but other than that, they should be the same. The colors in Basic are a little bland though, so you might not like it
 
Which of these two saves the most battery or are they the same in regards to power consumption?
Adaptive automatically optimizes colors based upon surroundings. The more saturated setting would most consume more power.

I always keep my phone on 0% brightness except for when I am outside so I am used to dull xd. Thanks for your response though :)
 
Your screen brightness would probably make more impact that between these display settings. Try adaptive. If you don't like, you can always switch back.
