I would strongly suggest prioritizing kerning. How text looks is the feature of a word processor, and I quit using LibreOffice a number of years ago because the text looked so hideous compared to anything else.

You're getting downvoted, but you have a point. Word processors are for writing documents; if you really care about typography in the final product, at some point you need to use a real typesetting tool. From what I can tell, most large companies and governments draft documents in Word and then send them to graphic designers to reformat in InDesign or something and publish as PDF. You can tell when a document has been typeset in Word; it feels unfinished and unprofessional, even if it looks better than a LibreOffice document.

I learned LaTeX because that was the "Word" of Linux when I was installing Slackware from diskettes.

And I don't regret it at all.

For me, I can't use it on macOS because it freezes for several seconds any time I open a document, try to scroll, etc. Thankfully I don't need to open doc and xls files much.

Last time i tried to use LibreOffice (~2 years ago) on OSX it was super slow/hanged when opening large CSV files while Excel on a virtual machine (same host) had 0 problems.

I used LibreOffice at work for two years (on linux) and it was good for most things, I used the powerpoint equivalent and it's definitely under-powered compared to MS but probably fine for 95% of people.

I also did the MS 360 thing once about 3 years ago and will never do that again.

My experience is that I’ve used libreoffice to convert unreadable .doc 2003 files to working .docx documents. In these (admittedly few) cases, (a more recent version of) word could not read the .doc files in a meaningful fashion.
