I think a question like this is better considered as “do you think X character is pro- or con-omnic.” Characters like D.Va and Zarya are still actively fighting omnics, and other characters like Sombra were turned orphan by the Crisis, so there are backgrounds there that a random person looking in on the situation from the outside can never have.
Even Darth’s response is complicated because it’s exactly what Torbjorn’s view was until he realized Bastion was not behaving according to programming. And at that realization, his opinion started to change.
