I have been extensively using LibreOffice alongside office 2019 (using Massgrave) And it is converging more and more.

I use it as my day tool as a lawyer, I use writer and calc alongside office tools and i see formatting issues coming less and less. This is after me using it day for 3-4 years daily.

Every update makes improvements.

Sure its "slow" at features but I'm not interested in "ai" features so it's fine.

It inherits all problems of desktop office, collaboration is hit as two people cannot work on the same file but it is "fine" for average user.

I follow the "meta onlyoffice comparison for writer/calc" and every 6 months or so it there is some improvement.

This is such an important tool to the level of curl but it doesn't have a marketing budget and it's not looking out for investors so "normies" don't know it exists or why it exists but it works.

The old memes of opening a word file and finding garbage is becoming less and less true. Cross compatibility with a moving target that is ms office is a Sisyphean task
