Someone more knowledgeable than me will likely join in soon, but depending on your application one op amp might be better than another because of
-
higher slew rate (which affects max frequency)
-
higher unity gain bandwidth (if you need to amplify a wide range on frequencies)
-
better common mode rejection ratio (for working with small signals and electrically noisy environments)
-
lower input bias current (for low- power applications)
-
higher input/ lower output impedance (to not load sensitive instruments/ distort signals)
And probably loads of other things… cost… thermal…

Thank you, perhaps it is the CMRR that I need to explore? Perhaps this explains the noise floor difference? Thank you.
