I work at a film rental company, and we do a hell of a lot of gimbal hires nowadays. Generally for high action stuff, we recommend getting a second operator and a controller, and using them to control it. Requires a fine hand, but the current market of gimbals just aren't intelligent enough to react in the right way.
Saying that, the steadyshot feature on the DJI Ronin gimbals is as close as it gets at the moment, and it's what I'll be using to film the next trials video I shoot when I can eventually arrange a weekend filming with Mr Beaden!
Which gimbal did you opt for?
