Last week, I wanted to solicit suggestions from my team at work, so I went to OneDrive, clicked the "Create or upload" button in the upper left, selected "Forms survey", created my survey, and sent the link out to my team. This week, I wanted to look at the results, so I went back to OneDrive... which had no way to get me to the form I had created... from OneDrive. I needed to go to forms.office.com to find the form, at which point I could export the results to Excel.
Meanwhile, Google Drive treats Forms like any other "document" that you can create and go back to from within that "one drive".
