Yeah, Impress is a mess. I use OnlyOffice for ppt files since I don't really care about performance in a slide editor. As for Writer, one more problem is that it is sometimes simply unbearably ugly. Just scrolling through a pretty small document creates rendering artifacts everywhere and the font rendering tends to randomly switch between passable and horrendous. If you're lucky though and that doesn't happen for you, it's actually pretty usable (ignoring format compatibility, of course, but that's also MS's fault).
