Two advantages of Gutenburg that both of you seemed to miss:
- Gutenburg loads faster than ACF, and will continue to load faster as it becomes more part of core
- ACF (or any additional plugin) adds a dependency, increases the attack surface, and adds more requests than would be needed if you were just using something already in core
These might be comparatively small advantages, but over time it seems they will become bigger (and may already have done since this conversation).
I’d be interested to know what either of you would have to say about those points.
