The all singing all dancing styles are designed for home hobby players who want to sound great without the wait, (Arrangers are nothing more than advanced versions of the easy play features of organs) pro musicians use them sparingly so that they can develop their own style, as otherwise (As you say) they sound like everyone else, which basically turns them into Karaoke Players.

The most disappointing thing these days is that people will tell you want instrument is being played by the sound/style, but won’t have a clue who the player is, whereas previously everybody identified the player by his style (No matter what instrument he was playing) which is always preferable. (Technology is a great servant, but too many players have let it become the master)
