Type of campaign is also a factor. My advice is maybe less helpful for dungeon or hex crawls. That said, lots of people really enjoy Dungeon World, which is D&D done PtbA style, so it's not useless either. What I specifically have been messing around with ideas from FATE and PtbA for is to run urban intrigue campaigns. I wanted more handles for social interaction, I wanted more player knowledge of NPCs and factions off the hop, I wanted a reputation system and I generally wanted the game to be more character driven in general. So I went looking for ideas and mechanics that matched what I wanted to do.
That process is exactly what I would suggest to anyone else - make a list of what you want to be able to do better or differently, and then find ideas that will work for you. In my case it did end up reducing prep in a couple of ways, but I'm not sure that would be the case for everyone, I think it would depend on the exact changes made.
