Interesting enough for me, I degoogled around 2005. And just now I have to use their online office tools and mail. Its horrific experience. (1) gmail is ugly and unproductive- not even possible to attach another mail to an email, seriously? (2) Calendar - omg, what is this. Its clunky, invites are unreadable and difficult to parse. Want to send a quick note that you are running late? There is no mail integration with the calendar... (3) Sharing - everyone over shares documents, the UI encourages, sometimes even silently grants powerful permission to others. So people have access to things they shouldn't- this is a real security issue in my opinion. (4) list goes on...

I really never thought I would miss Microsoft Office, but GSuites really makes me miss Office.
