Well, taking the actual differences aside as all platforms have their own pros/cons. Once the platform has been chosen for whatever reasons. The question is, do other cloud engineers tend to simply try helping out and resolve the problem or just throw comments about one or the other being better.

I understand the arguments at design level where the task is to choose the right platform for the job.

What I'm seeing is that AWS engineers tend to have that "AWS is the best of the best of the best SIR" attitude like we've seen in one of the scenes of Men in Black.
