I'm with DonM (and others) in that mostly I use general styles. I try to find (for example) an 8-beat style (from the many onboard) that seems to "work well" for a given song, even if it's not exact.

There are a few exceptions; someone gave me a great style for "In The Mood" that I now use. I also use a few others, can't think of them now, for songs that (as other said) have an unusual or unique hook or rhythm to them. Oh, I bought one a long time ago that is great for "Time Is Tight", so I use that song-specific one.

Probably ~95% of the time, I find a general styles that works well for each song that I set up up Registrations for ...
