I do find it better. Cranks brightness up more and faster when moving to sunlight. Previously I found it didn't get bright enough and took too long to adjust.

EDIT: Not sure whether this has anything to do with the 6/+ though, might be iOS 8.
 
Agreed. This is the first iphone since the first where I am actually using this feature. It's perfect.

I think it's the Hardware. I upgraded to iOS 8.0.0 on my 5s and the Auto Brightness still acted the same.
