I LAUGH at silly FUD like "you can't run a business without MSOffice", "You can't read documents ", "format compatibility problems!!", because that all is just FUD.
If I ever (rarely, maybe 4 times total) receive a price file or spec that is unreadable by LibreOffice, I just ask to resend it to me in some open format cause I lack the software to open their proprietary file. And I did received it in a PDF or .odt every single time I asked.
That said, I liked the software more in their OOo days. When it became LibreOffice it became somehow more buggy and ugly. OOo with the right icon pack was very neat and had a superior interface to MSOffice. LibreOffice icons got uglified and are no longer pleasant to look at, and combined all looks... Worse.
Their online efforts are also disastrously bad. LibreOffice Online is based on a flawed idea to run LO on a server and deliver rendered images to a user. It works super shitty bad. They should have just made a web-first editor for OpenDocument file format, with concurrent editing. (Maybe when I'm finally done with the XMPP I'll look for funding to make just this. ... )
