A bit early, but let's get it started! How does the Canon EOS R compare to the 5D Mark IV?
I admit, this is for completely self-serving reasons, but I'm sure the feedback can be useful to others stuck between choosing one or the other.
EOS 5D4 Pro/Cons vs R

+Larger buffer
+dual card slots
+built-in GPS

I'll be happy to update this first post as necessary with feedback provided from the comments.
