I have used deckset for all of my presentations[1]. It's fantastic, and forces you to follow Zach Holman's rules[2] about slide typography, which is basically "you can't go too big."
The presentations look wonderful. Zach has constantly been my inspiration to make better slides. Almost ALL my slides[0] incorporate some of his teachings :)
