i've only read 3 mangas, Naruto, One Piece and Fairy Tail
and i've never even seen fma as an anime
but the thing is the art style is so different from one to the next that it would really come down to whether you prefer semi-realistic drawing or more cartoon-ish drawing because all 3 look really good in my opinion but OP and FT are much more cartoon like drawings (people with huge features, oddly shaped faces and bodies) where naruto looks a little bit more realistic (people's bodies are more or less uniform, with only diff being height, weight, more or less muscular etc.)
that being said i personally like the FT manga but OP anime. Naruto isn't very consistent with anime, everyone know's how terrible pain looked for those 3 seconds against naruto, but the manga is very good and usually is and since FT wasn't a part of your list i will say Naruto because OP manga can be difficult to understand at times
