I use linux day in day out at home and at work. Typing this on linux. It’s my go to platform, my daily driver.
Having said that I recently tried to create a presentation in libreoffice and had to give it up and use ppt/windoze (can access via cloud).
For my personal preference I won’t be using Libreoffice for any more presentations - in fact started another one today using PPT.
Not an expert at it, as I mostly use Calligra for its Visio emulator (Flow), but from the limited play I've done with it, it looks pretty good to me.
