Other than Google, what are other competitors that worth evaluating?
Unironically Proton. Seems like they are slowly building their own suite of office tools.
Canva is a go to over Microsoft and Adobe for a huge crowd of people
Collabora Online
For which feature?
How people in companies really need the features of Word, Excel and PowerPoint?
I often see people using space to right align a date, the pros use tabs.
Zoho and Collabora spring immediately to mind.
