My current game crush is Fate. I like the dice system is pretty weighted towards average. I like that it encourages a more writer's room style. I like that you can just start with your concept instead of the like "I'll take 2 levels of this, two levels of that, and then after four levels of foobar my character really comes online". I like that it's a generic system so you can play any setting.

My main problem is finding players who are eager and able to play it. The last time I tried I dropped the ball a little, but even aside from that the players didn't really seem to get it, either.
