Where I work (US Department of Defense), we depend on PowerPoint more than anything. We recently got O365 which includes the PowerPoint web application, but the web application is still very weak compared to the desktop application. Anything beyond editing some text on a slide, or creating a very simple (mostly text) slide, in the web application is just horrible if not impossible. This is really a shame, because the ability for multiple people to open a PowerPoint file in O365 and do simultaneous editing is an amazing leap forward. Version control has always been a problem for us as we endlessly email PowerPoint files back and forth, or store them on SharePoint or simple file servers.
I've mostly used LibreOffice (and OpenOffice before that) on my personal machine at home, but I wouldn't dare depend on it to handle the complex PowerPoint files that we pass around at work.
Edited to add: I guess we equally depend on fillable PDFs (often digitally signed with our smart cards). For that, I gave up on trying to find a good native solution in Linux after Adobe stopped making Acrobat Reader available in 2013.
