I've used this 'suggestion' workflow in azure devops. https://devblogs.microsoft.com/devops/introducing-the-new-pu...
I didn't know about it at all! That looks like exactly what I wanted.
So I'm back to liking dev-ops and github code reviews identically!
Commenting feels so much better. You can comment on entire files, and you can leave review comments that actually "block" (rather than just get appended to the conversation)
I use it every day and don't have any issues with the review system, but to me it's very similar to github. If anything, I miss being able to suggest changes and have people click a button to integrate them as commits.
