I like that it is easy to use, works with slack out of box (no need install anything). It has multiple options so many ways we can customize our interface as per needs/preferences or what are using currently internally at their organisation / work place etc., The ability to embed media content into documents makes this tool very useful when creating docs online which will be viewed by users who do not have access otherwise! Some times there could also lag while working if too much activity going around within an organization - maybe due server traffic issues? Also sometimes some pages might get stuck where they dont reload automatically after submitting changes made! But overall its quite good product available free via google cloud platform without any limitations unlike other subscription products i had used previously such MS WORD 2016 & Sharepoint Online Services 2013 before Google Cloud Platform release these services!! Definitely recommendable one.
