This is probably great software. But the design, both of the site and the office software, looks so dated, it doesn’t even tempt me to try it
It is actually very, very janky and behaves like someone tried to reimplement ~15 years old Office UI in JavaScript. Not in a good way.
I really, really want them to be successful, but I cannot pretend it's a pleasure to use at all.
Working with data I need to be objective, and while thinking objectively I prefer brutal/minimal ist UIs
I don't care about dated looks. I do find MS Office's pressure to use OneDrive frustrating and annoying. Honestly, older UIs for office suite products just feel more direct and responsive than the clever ribbon bars. Excel used to be svelte (25 years ago or more...) Now it feels bloated and clumsy. LibreOffice Calc (same parentage as Collabora Office) feels more like Excel used to feel. Similar complaints about Word.
