[Q] Camera quality: superior auto vs 15.5mp manual topic

Hi all. I jus bought this phone, it's great and all, but camera didn't deliver as expected. Moved from LG G3 to Z3 compact, and camera is of lower quality it seems. Some people say that superior auto mode takes better pictures, some say that manual mode take better pictures. I'm not specially interested in detail, it is obvious that 20mp shots do have a lot more detail than 8mp superior auto shots. I am specially interested in noise, sharpness and colour balance. Most of my pics are shot in low light without flash (at home, in the office, in pubs and coffe shops, etc). What mode does deliver less noise and more acurate colours? Manual or Superior auto? I have mixed results in my testing. Thanks allot
