I've only been using this for a little bit of time, but I just wanted to put my thoughts down and say it's really impressive. If you get your hands on it, definitely try using the AI beautify slide feature and import your existing PowerPoint presentations—it will regenerate them in whatever template style you want. I was really impressed. It's worth it for this feature alone.

On top of that, it looks like a full-out, well-featured presentation creator. You can use your own custom templates, and it was able to import my data charts seamlessly. If you don’t like the way a slide is stylized, there are plenty of options to switch up the look. I've used PowerPoint for a least a decade, I'll definitely be using this going forward. Bonus, you can export your presentation in .pptx format. Overall, a great experience so far!
