Works best for me
I work in an environment where I share a lot of my work with others. Ive worked with every major platform. I use Google Doc, Slides, Sheets since I can produce high quality documents and share them easily. I push the boundaries on most presentation software. I found Slides, while not having all the "bells and whistles" of other presentation software, delivers what is needed with sufficient quality. Again, I share most of my work with others. Nothing is as easy as Slides. I also work where wifi is always available and I use different computing platforms based upon the meeting. Slides works for me! If your situation is different, your mileage may vary.
