I agree with Andrea'a sugestions for avoiding style-playing being boring. When I play with "finesse", for myself, I also tend to simplify the automatic arrangements, muting some tracks. But most of the time, in my jobs I'm asked to speed up and to be as noisy as I can (yuk!..).

I also agree that some playing techniques are brand/model-related, so they only work in a particular brand/model. But others can be used in all brands. One of them that I do frequently (in pop/rock tunes it works well) is to interrupt the automatic accompaniement, and, in bass/melody split mode (with the drum machine always on), do a bass solo with my left hand, possibly with some comping with the right hand (acoustic or electric piano). This can be easily done in all keyboards. In Yamaha keyboards you can cut down the auto stuff temporarily by pressing three consecutive keys (for example, C/B/Bb) - I love this feature too!
