Defense auto flip play on or off? Which is better?

Is it better to have the auto flip play set to on or off? My only problem with it set to on is I'll pick a play out of nickel 3-3 cub/wide and the play art will show for example that my LOLB Khalil Mack will be rushing the QB but when the huddle breaks sometimes it will be the ROLB or RE that's rushing the QB while Mack will be in coverage. I'm guessing auto flip set to on is best for players that arent as advanced? Is there a way that you can tell when your opponent flips their offensive play before the huddle breaks cause I know you can tell when they start flipping the play at the Los cause all the players will move and be in motion. Is auto flip just a safe measure for most players and does it really matter?For instance  If I got Lawrence Taylor you would think that you would want him rushing the QB for most plays instead of playing coverage but with auto flip on then sometimes you would have to make the adjustments at the Los if your opponent flips their play. Hopefully I made sense with this post. Just wondering if players turn off auto flip or if they just leave it set to on?
