My stress level just went up after opening gmail.com after few years since I switched to Inbox.
Being used to just swiping emails that I didn't need to attend, I didn't realize they were still in "unread" status.
Now when I opened Gmail, I see:
Social 190
Updates 4,856
Forums 3,329
Promotions 4,214
The worst part is that I cannot see which of those "Unread" emails are pinned in Inbox.And.. we cannot Pin emails in Gmail the same way as in Inbox :( [I have already read the "Pin emails" section in https://support.google.com/inbox/answer/9117840, but starring/labeling/searching doesn't give the convenience that Inbox pinning did.]
I'll also miss all the rich email rendering of emails like shipping tracking, flight tickets, appointments, etc.
Alas..

Update: And of course Google would discontinue Inbox. Inbox did not have ads, but Gmail has freaking ads!
