The trilogy is better story and character wise
Andromeda's combat shyts all over the trilogy
Gonna highly disagree with Andromeda having better combat than 3.
Andromeda having better combat than 2 is more debatable but it depends on how you played ME2. If you played on normal difficulty and didn't use or like the squad elements, sure, Andromeda is better. I think ME2 is more in depth when it comes to that and is harder to master.
