Yes exactly. I definitely sympathize with the other complaints: the newer Word UI is pretty garbage (I truly do hate the ribbon bar). There is a bit extra padding in the newer UI. But really, it all comes down to the PPI which seems obvious.
What's more, I feel like people aren't bothering to recognize that the newer UI shows the document as it would be laid out on a page when you print it. This is really helpful if you write documents to be printed. It seems clear that the newer UI, while there are elements I dislike, is more useful.
