Fantasy AGE
I've run some Dragon Age games, which uses the same game engine. Overall I really like it, but what I noticed is that the combat takes longer than D&D, even though it's less complex than D&D 3.5e or Pathfinder. At least in the experiences I had, everyone has a LOT of hit points so it takes more time to whittle down a foe. I don't know if they addressed that in Fantasy AGE or not.
The stunts are my favorite feature of the game system. They're a lot of fun, they make the game more cinematic, and they allow players a bit more flexibility in what they can do.
