Maybe I am just too dumb but I always found pull requests hard for making small commits. Somehow PRs always ended up being on the bigger end. We even tried these stacked PRs but it was quite confusing.

In the end we moved to Gerrit and never looked back. We are not super experienced yet but I'd say our commit quality went up by quite a bit.
