It’s good that LibreOffice exists and it can be a decent replacement for someone writing a simple document every once in a while. I can not take anyone seriously who claims it is anywhere near as good as the MS stuff. Recently I created a presentation in Impress and it was hell on earth. I ran into multiple bugs and handling formatting was just horrid working with the master/template slides (or whatever they are called) was essentially impossible.
Currently working with OnlyOffice which works better by a considerable margin.
