I try to use it all - styles -factory or self modified (song specific or not), SMFs, mp3, dedicated button to kill all acc tracks but bass and drums, etc. ...
I've modified styles to switch from Latin to Swing or whatever, but changing meter - 4/4 to 3/4 takes more than that ... for those situations I will line up the two styles one after the other either in the User Style section or in the Songbook or a Playlist and switch the meter as I want ...

This was all SO simple years ago with my technics Kn6000 and its Panel Memory (registrations) ... gave me 8 different setups per style ...

Of course each of us should use what we are comfortable and happy with ...
