I actually do use beamer for most presentations, but all universities I’ve worked at only ever provided templates for PowerPoint. My solution to this has been to just write a .sty file that makes it look similar (and leaves out the over-designed garbage that the templates tend to contain).

Edit: I’ve tried reveal, too. Didn’t hate it, but it makes some things ridiculously difficult (e.g., handouts or “overlay-style” animations).
