One big disadvantage of writing in LaTeX compared to writing in other software, such as Word, is that its absence of track changes. Although there are ways to do track changes, such as the online tex-editor Sharelatex or the trackchanges package, I have sticked to commenting out deleted parts of the text, or by highlighting new passages in red.
I just came across this cool website on which you can compare different tex codes, e.g. before and after one of your co-authors worked on a text. On this website, you simply paste the original and the revised version, and you will receive a tex-code to generate a “track changes” document, which exactly highlights deleted and new text.
