I try to avoid using MS products (not hate, just trying to favour free software), but I had to learn extensively about Office last year and I really enjoyed the UX. It has some powerful features for working with animations, transitions and effects. Take this example [1] -I don’t think it’s even possible to do in Google Slides, which finds its power by being more simple and multiplatform. So it depends on your needs, which also applies to Beamer.
