Regardless of the interface GMAIL uses, I've forwarded all my personal gmail e-mails to my secondary e-mail at outlook.com. It's a much better interface IMHO.
At work, we use G Suite for Business and most staff almost never use the Gmail interface. Almost everybody uses Outlook as their mail client.
We hate gmail so much that we are switching to Office 365 e-mail. Now I can finally accept meeting invitations within the Outlook mail client (which is designed to work with Office 365/Exchange in the first place) and have it update my calendar!
