So many congregations use PowerPoint for their worship slides—mostly because they already have it, and know how to use it. However, I recommend trying ProPresenter. You can download a free version from their website. The free version is pretty well fully functioning. The major difference from the pay version is that it puts up a watermark on your screen from time to time. So you likely won’t be able to use it for worship until you pay for the software.

I have put together a short Intro to ProPresenter video if you would like to check it out:
