i use neither animations nor transitions. but i do extensively use movies (which have a horrible support in Impress), and i use lots of equations (which you can enable using third-party plugins in Impress, but working with them is very difficult).

i’ve been bitten twice when i’ve been traveling on a conference and had to quickly put up slides in Impress, and ended up not being able to do what i wanted because of all of its limitations. i ended up using reveal.js, but that also has its own drawbacks, e.g., the lack of UI, which i can use to quickly fine-tune arrows, text positions etc.

I can give you reasons I have for not installing Linux on one of my laptops:

• Intel graphics support, or the absence of it;

• decent touchscreen support (Windows Ink);

• WSL which I use with NixOS, and it does simplify most of my dev needs;

• unfortunately, Adobe apps which I still heavily rely on (I’d wish I had an alternative),

• PowerPoint (again, I’d wish I had an alternative).

If you want to comment: "oh but have you tried Affinity, Pixie, Only Office, Libre Impress, reveal.js, {enter your fav presentation/photo editing tool} – yes I have, and no, unfortunately, it’s not even close. Also, to be clear, I’ve never paid, and never will for the Windows/Adobe products.
