For stills, I only use ML when shooting in Live View. That means when I'm using a tripod, which means I don't use it often. But like many camera features, it's useless until it's the perfect tool. And I use it almost continuously when shooting video. I've messed around with the bracketing and intervalometer features, but haven't really produced any CiC-worthy results yet. So far, I like it. The UI lacks polish, but it works very well once you understand its quirks.
