I switched, because I find the way they force you into one drive rather obnoxious. I tried a bunch and settled on WPSOffice, because it worked the best, but it still ended up being annoying and I just switched back and put up with it.

I've had pretty good luck with replacing Windows with MacOS, Acrobat with PDFExpert, Outlook with Superhuman, Google with Kagi and never looked back, but Microsoft Office works quickly, is smooth, works across many platforms. The other solutions are clunky in many different ways and I've tried a bunch of them.

I actually have licenses from work, my wife has licenses from school, I have a personal family license for my family. I was literally paying to use WPSOffice on top of it and it just doesn't work as well. Something about the way the interfaces just aren't as responsive in terms of cell sizes just makes everything super clunky in everything from Numbers to WPSOffice

I thought about this a little bit more as it's been a while, but I think the reason Office is so dominant is that it's really 5 different pieces of very different complicated software. It's easy to knock off Word, but to copy Word, Excel, Powerpoint and make them all great, and compatible is very difficult.

I think if you separated them and chose the best alternative word processor and best alternative spreadsheet and best alternative presentation software, maybe you would have a better shot at replacing them. WPSOffice has the best excel, but powerpoint isn't as good, etc.
