So here is my issue:I would go for the 5DIV:
1. Dual pixel AF makes the camera much more versatile if viewfinder shooting is difficult. Face tracking makes shooting at large apertures easier.
2. Dynamic range.
4. GPS and Wifi
5.smaller and more manageable files for editing and storage. 30 megapixels are plenty for most scenarios.
1. Would never use.
2. This I consider an advantage I would use for 5DIV
3. I never use ISO over 6400 because it looks terrible IMO.
4. Would never use either.
5. Not a concern at all.
For my use case so far DR is the only significant advantage I am coming up with, but it is offset by the resolution loss
